9 Detailed Description
9.1 Overview
The SNx4AHCT574 devices are octal edge-triggered D-type flip-flops that feature 3-state outputs designed
specifically for driving highly capacitive or relatively low-impedance loads. These devices are particularly suitable
for implementing buffer registers, IO ports, bidirectional bus drivers, and working registers.
Regarding the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels of the data (D)
inputs. A buffered output-enable (OE) input places the eight outputs in either a normal logic state (high or low) or
the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines
significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without
interface or pull-up components.

10 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.
10.1 Application Information
The SN74AHCT574 is a low-drive CMOS device that can be used for a multitude of bus interface type
applications where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and
undershoot on the outputs. The input switching levels have been lowered to accommodate TTL inputs of 0.8-V
VIL and 2-V VIH. This feature makes the device ideal for translating up from 3.3 V to 5 V. Figure 4 shows this type
of translation.

10.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus
contention because it can drive currents that would exceed maximum limits. The high drive will also create fast
edges into light loads; therefore, routing and load conditions should be considered to prevent ringing.
10.2.2 Detailed Design Procedure
1. Recommended input conditions
– Rise time and fall time specs: See (Δt/ΔV) in the Recommended Operating Conditions table.
– Specified High and low levels: See (VIH and VIL) in the Recommended Operating Conditions table.
– Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.
2. Recommend output conditions
– Load currents should not exceed 25 mA per output and 75 mA total for the part.
– Outputs should not be pulled above VCC.

11 Power Supply Recommendations
The power supply can be any voltage between the MIN and MAX supply voltage rating located in the
Recommended Operating Conditions table.
Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single
supply, 0.1 μF bypass capacitor is recommended. If there are multiple VCC pins, 0.01 μF or 0.022 μF is
recommended for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different
frequencies of noise. A 0.1 μF and 1 μF are commonly used in parallel. The bypass capacitor should be installed
as close to the power pin as possible for best results.
12 Layout
12.1 Layout Guidelines
When using multiple bit logic devices inputs should not ever float.
In many cases, functions or parts of functions of digital logic devices are unused, for example, when only two
inputs of a triple-input AND gate are used or 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 5 are the 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
should be applied to any particular unused input depends on the function of the device. Generally they will be
tied to GND or VCC; whichever makes more sense or is more convenient. It is generally acceptable to float
outputs unless the part is a transceiver. If the transceiver has an output enable pin, it will disable the outputs
section of the part when asserted. This will not disable the input section of the IO’s so they cannot float when
disabled.
