DM74LS574 Octal D-Type Flip-Flop with 3-STATE Outputs

March 1988

Revised March 2000

DM74LS574

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

General Description

The DM74LS574 is a high speed low power octal flip-flop

with a buffered common Clock (CP) and a buffered com-

mon Output 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 DM74LS374

except for the pinouts.
