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