SNx4HC74 Dual D-Type Positive-Edge-Triggered Flip-Flops With Clear and Preset
1 Features
3 Description
•
•
•
•
•
•
The SNx4HC74 devices contain two independent Dtype positive-edge-triggered flip-flops. A low level at
the preset (PRE) or clear (CLR) inputs sets or resets
the outputs, regardless of the levels of the other
inputs. When PRE and CLR are inactive (high), data
at the data (D) input meeting the setup time
requirements are transferred to the outputs on the
positive-going edge of the clock (CLK) pulse. Clock
triggering occurs at a voltage level and is not directly
related to the rise time of CLK. Following the holdtime interval, data at the D input can be changed
without affecting the levels at the outputs.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

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
A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of 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 on the positive-going edge of the clock pulse. Clock triggering occurs
at a voltage level and is not related directly to the rise time of the clock pulse. Following the hold-time interval,
data at the D input can be changed without affecting the levels at the outputs.
The resistor and capacitor at the CLR pin are optional. If they are not used, the CLR pin should be connected
directly to VCC to be inactive.
9.2 Typical Application
5V
5V
5V
SN74LVC1G17
SN74HC74
Figure 4. Device Power Button Circuit
9.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it
can drive currents that would exceed maximum limits. Outputs may be combined to produce higher drive, but the
high drive will also create faster edges into light loads. Because of this, routing and load conditions should be
considered to prevent ringing.
9.2.2 Detailed Design Procedure
1. Recommended Input Conditions:
– For rise time and fall time specifications, see (Δt/ΔV) in Recommended Operating Conditions table.
– For specified high and low levels, see (VIH and VIL) in Recommended Operating Conditions table.
– Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.
2. Recommended Output Conditions:
– Load currents should not exceed 25 mA per output and 50 mA total for the part.
– Series resistors on the output may be used if the user desires to slow the output edge signal or limit the
output current.

10 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the
Recommended Operating Conditions table. Each VCC terminal should have a good bypass capacitor to prevent
power disturbance. For devices with a single supply, a 0.1-μF capacitor is recommended and if there are multiple
VCC terminals then .01-μF or .022-μF capacitors are recommended for each power terminal. 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 terminal as possible
for best results.

11 Layout
11.1 Layout Guidelines
When using multiple bit logic devices, inputs should not float. 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-buffer gates are used. Such input pins should not be left unconnected because the
undefined voltages at the outside connections result in undefined operational states.
Specified in Figure 6 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 acceptable 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.
