54F/74F574

Octal D-Type Flip-Flop with TRI-STATE Outputs

General Description

Features

Inputs and outputs on opposite sides of package

allowing easy interface with microprocessors

Useful as input or output port for microprocessors

Functionally identical to ’F374

The ’F574 is a high-speed, low power octal flip-flop with a

buffered common Clock (CP) and a buffered common Out-

put Enable (OE). The information presented to the D inputs

is stored in the flip-flops on the LOW-to-HIGH Clock (CP)

transition.

TRI-STATE outputs for bus-oriented applications

This device is functionally identical to the ’F374 except for

the pinouts.
