Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

MM74HC374 3-STATE Octal D-Type Flip-Flop

MM74HC374

3-STATE Octal D-Type Flip-Flop

General Descript ion

The MM74 HC374 high speed Octal D-Type Flip-Flops uti-

lize advanced silicon-gate CMOS technology. They pos-

sess the hi gh noise immun ity and l ow power consu mption

of standard CMOS integrated circuits, as well as the ability

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

capability and t he 3-STAT E featu re, th ese de vices are ide-

ally suited for interfacing with bus lines in a bus organized

system.

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

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

storage elements.

The 74H C logic f amily is sp eed, functio n, and pi nout com -

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

protect ed from damage due to static di scharge by in ternal

diode clamps to VCC and ground.

Features

■Typical propagation delay: 20 ns

■Wide operat i ng voltage range: 2–6V

■Low input current: 1

■Low quiescent current: 80

■Compatible with bus-oriented systems

■Output drive capability: 15 LS-TTL loads

Devices also available in Tape and R eel. Sp ec if y by appending the suffix lett er “X” to th e ordering co de.
