74F574

Octal D-Type Flip-Flop with 3-STATE Outputs

General Description

The 74F574 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.

This device is functionally identical to the 74F374 except

for the pinouts.

Features

s Inputs and outputs on opposite sides of package

allowing easy interface with microprocessors

s Useful as input or output port for microprocessors

s Functionally identical to 74F374

s 3-STATE outputs for bus-oriented applications

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
