MM54HC76/MM74HC76 Dual J-K Flip-Flops

with Preset and Clear

General Description

These high speed (30 MHz minimum) J-K Flip-Flops utilize

advanced silicon-gate CMOS technology to achieve, the low

power consumption and high noise immunity of standard

CMOS integrated circuits, along with the ability to drive 10

LS-TTL loads.

The 54HC/74HC logic family is functionally as well as pin-

out compatible with the standard 54LS/74LS logic family.

All inputs are protected from damage due to static dis-

charge by internal diode clamps to V

and ground.

Features

Each flip-flop has independent J, K, PRESET, CLEAR, and

CLOCK inputs and Q and Q outputs. These devices are

edge sensitive to the clock input and change state on the

negative going transition of the clock pulse. Clear and pre-

set are independent of the clock and accomplished by a low

logic level on the corresponding input.

Typical propagation delay: 16 ns

Wide operating voltage range

Low input current: 1 mA maximum

Low quiescent current: 40 mA maximum (74HC Series)

High output drive: 10 LS-TTL loads
