Dual D-Type Flip-Flop with Preset and Clear

General Description
The MM74HC74A utilizes advanced silicon-gate CMOS
technology to achieve operating speeds similar to the
equivalent LS-TTL part. It possesses the high noise
immunity and low power consumption of standard
CMOS integrated circuits, along with the ability to drive
10 LS-TTL loads.
This flip-flop has independent data, preset, clear, and
clock inputs and Q and Q outputs. The logic level
present at the data input is transferred to the output during
the positive-going transition of the clock pulse. Preset
and clear are independent of the clock and
accomplished by a low level at the appropriate input.
The 74HC logic family is functionally and pinout compatible
with the standard 74LS logic family. All inputs are
protected from damage due to static discharge by internal
diode clamps to VCC and ground.

Features
Typical propagation delay: 20ns
Wide power supply range: 2V–6V
Low quiescent current: 40μA maximum (74HC Series)
Low input current: 1μA maximum
Fanout of 10 LS-TTL loads
