Features

Description

• Buffered Inputs

The Harris CD74HC374, CD74HCT374, CD74HC574 and

CD74HCT574 are Octal D-Type Flip-Flops with Three-State

• Common Three-State Output Enable Control

• Three-State Outputs

[ /Title

Outputs and the capability to drive 15 LSTTL loads. The eight

edge-triggered flip-flops enter data into their registers on the

LOW to HIGH transition of clock (CP). The Output Enable

(OE) controls the three-state outputs and is independent of

the register operation. When Output Enable (OE) is HIGH the

outputs will be in the high impedance state. The 374 and 574

are identical in function and differ only in their pinout

arrangements.
