MM74HC374N intecrate circuits

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

advanced silicon-gate CMOS technology. They possess

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 ideally

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 requirements,

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 the other inputs and the state of the

storage elements.

The 74HC logic family is speed, function, and pinout compatible

with the standard 74LS logic family. All inputs are

protected from damage due to static discharge by internal

diode clamps to VCC and ground.
