SN74HCS72-Q1 Automotive Qualified Schmitt-Trigger Input Dual D-Type
Negative-Edge-Triggered Flip-Flops With Clear and Preset
1 Features
3 Description
•
This device contains two independent D-type
negative-edge-triggered flip-flops. All inputs include
Schmitt-triggers, allowing for slow or noisy input
signals. A low level at the preset (PRE) input sets the
output high. A low level at the clear (CLR) input
resets the output low. Preset and clear functions are
asynchronous and not dependent on the levels of the
other inputs. When PRE and CLR are inactive (high),
data at the data (D) input meeting the setup time
requirements is transferred to the outputs (Q, Q) on
the negative-going edge of the clock (CLK) pulse.
Following the hold-time interval, data at the data (D)
input can be changed without affecting the levels at
the outputs (Q, Q).

8.3 Feature Description
8.3.1 Balanced CMOS Push-Pull Outputs
A balanced output allows the device to sink and source similar currents. The drive capability of this device may
create fast edges into light loads so routing and load conditions should be considered to prevent ringing.
Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without
being damaged. It is important for the output power of the device to be limited to avoid damage due to overcurrent. The electrical and thermal limits defined the in the Absolute Maximum Ratings must be followed at all
times.
8.3.2 CMOS Schmitt-Trigger Inputs
Standard CMOS inputs are high impedance and are typically modeled as a resistor in parallel with the input
capacitance given in the Electrical Characteristics. The worst case resistance is calculated with the maximum
input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage current, given in the
Electrical Characteristics, using ohm's law (R = V ÷ I).
The Schmitt-trigger input architecture provides hysteresis as defined by ΔVT in the Electrical Characteristics,
which makes this device extremely tolerant to slow or noisy inputs. While the inputs can be driven much slower
than standard CMOS inputs, it is still recommended to properly terminate unused inputs. Driving the inputs slowly
will also increase dynamic current consumption of the device. For additional information regarding Schmitt-trigger
inputs, please see Understanding Schmitt Triggers.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The SN74HCS72-Q1 is an ideal device for taking a CAN wake-up request and converting it to a power supply
enable due to its low power consumption and noise rejecting inputs, which eliminate false triggers. CAN
communication can occur when the vehicle ignition is off. Therefore, many circuits are designed to work in a
standby or low power mode. Because a CAN wake-up request causes the RX pin to pulse LOW, the
SN74HCS72-Q1 will trigger off the falling edge enabling the power for the CAN controller. Then the CAN
controller powers on for the incoming communication. When communications are finished, the controller sends a
reset pulse to the SN74HCS72-Q1 and CAN transceiver putting the circuit back into a standby mode.

9.2.1 Design Requirements
The SN74HCS72-Q1 device allows flexibility by having complementary outputs for active-high or active-low
enables. The supply should be selected such that the device is always powered along with the CAN transceiver.
The same supply for both devices is recommended.
With the SN74HCS72-Q1, a power on reset circuit only requires a resistor (R) and capacitor (C) to create a
delay. The R and C values create a delay that is approximately 2.2×RC. In this application, it is desired to have
the output (Q) in the HIGH state at startup, so R1 and C1 are connected directly to the CLR pin, as shown in
Figure 12. A second resistor is needed to limit the current into the CAN controller when it sets the circuit back
into standby mode. It is required for the R1 resistor to be at least ten times larger than R2 to avoid a divider
circuit (R2 ≤ 10R1).
The D input can be tied either to VCC or ground depending on the desired implementation. In this example, it is
tied to VCC to obtain a HIGH signal from Q when a wake-up request occurs.

Typical Application (continued)
9.2.1.1 Output Considerations
In general, the load needs to be considered in the design to determine if the device will have the capability to
drive it. For this application, we assume that the flip-flop output is transmitting over a relatively short trace (under
10 cm) to a CMOS input.
Primary load factors to consider:
• Load Capacitance: approximately 15 pF
– See the Switching Characteristics section for the capacitive loads tested with this device.
– Increasing capacitance will proportionally increase output transition times.
– Decreasing capacitance will proportionally decrease output transition times, and can produce ringing due
to very fast transition rates. A 25-Ω resistor can be added in series with the output if ringing needs to be
dampened.
• Load Current: expected maximum of 10 µA
– Leakage current into connected devices.
– Parasitic current from other components.
– Resistive load current.
• Output Voltage: see Electrical Characteristics for output voltage ratings at a given current.
– Output HIGH (VOH) and output LOW (VOL) voltage levels affect the input voltage, VIH and VIL, respectively,
to subsequent devices.
9.2.1.2 Input Considerations
The SN74HCS72-Q1 has Schmitt-trigger inputs. Schmitt-trigger inputs have no limitation on transition rate,
however the input voltage must be larger than VT+(max) to be guaranteed to be read as a logic high, and below
VT-(min) to be guaranteed to be read as a logic low, as defined in the Electrical Characteristics. Do not exceed the
values specified in the Absolute Maximum Ratings or the device could be damaged.
9.2.1.3 Timing Considerations
The SN74HCS72-Q1 is a clocked device. As such, it requires special timing considerations to ensure normal
operation.
Primary timing factors to consider:
• Maximum clock frequency: the maximum operating clock frequency defined in Timing Characteristics is the
maximum frequency at which the device is guaranteed to function. This value refers specifically to the
triggering waveform, measuring from one trigger level to the next.
• Pulse duration: ensure that the triggering event duration is larger than the minimum pulse duration, as defined
in the Timing Characteristics.
• Setup time: ensure that the data has changed at least one setup time prior to the triggering event, as defined
in the Timing Characteristics.
• Hold time: ensure that the data remains in the desired state at least one hold time after the triggering event,
as defined in the Timing Characteristics.
9.2.2 Detailed Design Procedure
1. Recommended Input Conditions:
– Input signals to Schmitt-trigger inputs, like those found on the HCS family of devices, can support
unlimited edge rates.
– Input thresholds are listed in the Electrical Characteristics.
– Inputs include positive clamp diodes. Input voltages can exceed the device's supply so long as the clamp
current ratings are observed from the Absolute Maximum Ratings. Do not exceed the absolute maximum
voltage rating of the device or it could be damaged.

10 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the
Absolute Maximum Ratings table. Each VCC terminal should have a bypass capacitor to prevent power
disturbance. For this device, a 0.1-μF capacitor is recommended. It is acceptable to parallel multiple bypass caps
to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The
bypass capacitor should be installed as close to the power terminals as possible for best results.
11 Layout
11.1 Layout Guidelines
In many cases, functions or parts of functions of digital logic devices are unused. Some examples are when only
two inputs of a triple-input AND gate are used, or when only 3 of the 4 channels are used. Such input pins should
not be left completely unconnected because the unknown voltages result in undefined operational states.
Specified in Figure 14 are rules that must be observed under all circumstances. All unused inputs of digital logic
devices must be connected to a high or low bias to prevent them from floating. The logic level that must be
applied to any particular unused input depends on the function of the device. Generally they are tied to GND or
VCC, whichever makes more sense or is more convenient. It is recommended to float outputs unless the part is a
transceiver. If the transceiver has an output enable pin, it disables the output section of the part when asserted.
This pin keeps the input section of the I/Os from being disabled and floated.
