3-STATE Octal D-Type Flip-Flop

signals are present at the other inputs and the state of the

storage elements.

General Description

The MM74HC374 high speed Octal D-Type Flip-Flops uti-

lize advanced silicon-gate CMOS technology. They pos-

sess the high noise immunity and low power consumption

of standard CMOS integrated circuits, as well as the ability

to drive 15 LS-TTL loads. Due to the large output drive

capability and the 3-STATE feature, these devices are ide-

ally suited for interfacing with bus lines in a bus organized

system.

The 74HC logic family is speed, function, and pinout com-

patible with the standard 74LS logic family. All inputs are

protected from damage due to static discharge by internal

diode clamps to V_CCand ground.

Features

■ Typical propagation delay: 20 ns

These devices are positive edge triggered flip-flops. Data

at the D inputs, meeting the setup and hold time require-

ments, are transferred to the Q outputs on positive going

transitions of the CLOCK (CK) input. When a high logic

level is applied to the OUTPUT CONTROL (OC) input, all

outputs go to a high impedance state, regardless of what

■ Wide operating voltage range: 2–6V

■ Low input current: 1 µA maximum

■ Low quiescent current: 80 µA maximum

■ Compatible with bus-oriented systems

■ Output drive capability: 15 LS-TTL loads
