HD74HC78

Dual J-K Flip-Flops (with Preset, Common Clear and

Common Clock)

Description

This flip-flop is edge sensitive to the clock input and change state on the negative transition of the clock

pulse. Each flip-flop has independent J, K, and preset inputs and Q and

outputs. Two flip-flops are

controlled by a common clear and a common clock. Preset and clear are independent of the clock and

accomplished by a low logic level on the corresponding input.

Features

•

High Speed Operation: t

(Clock to Q) = 20 ns typ (C

= 50 pF)

•

High Output Current: Fanout of 10 LSTTL Loads

•

Wide Operating Voltage: V

= 2 to 6 V

•

Low Input Current: 1 µA max

•

Low Quiescent Supply Current: I

(static) = 2 µA max (Ta = 25°C)
