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.
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.
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
CC
and ground.
