High-Speed CMOS Logic Octal D-Type Flip-Flop,

3-State Positive-Edge Triggered

February 1998 - Revised May 2004

Features

Description

• Buffered Inputs

The ’HC374, ’HCT374, ’HC574, and ’HCT574 are octal D-type

flip-flops with 3-state outputs and the capability to drive 15

• Common Three-State Output Enable Control

• Three-State Outputs

[ /Title

(CD74

HC374

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 3-state outputs and is

independent of the register operation. When OE is HIGH, the

outputs are in the high-impedance state. The 374 and 574 are

identical in function and differ only in their pinout arrangements.

• Bus Line Driving Capability

• Typical Propagation Delay (Clock to Q) = 15ns at
