HD74HC76

Dual J-K Flip-Flops (with Preset and Clear)

Description

Each flip-flop has independent J, K, preset, clear, and clock inputs and Q and Q outputs. This device is

edge sensitive to the clock input and change state on the negative going transition of the clock pulse. Clear

and preset are independent of the clock and accomplished by a low logic level on the corresponding input.

Features

•

High Speed Operation: t_pd(Clock to Q) = 21 ns typ (C_L= 50 pF)

High Output Current: Fanout of 10 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 2 µA max (Ta = 25°C)

Note: 1. Q and Q will remain HIGH as long as Preset and Clear are Low, but Q and Q are unpredictable,

if Preset and Clear go HIGH simultaneously.
