MM74HC74A
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 immu-
nity and low power consumption of standard CMOS inte-
grated 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
s Typical propagation delay: 20 ns
s Wide power supply range: 2–6V
s Low quiescent current: 40 µA maximum (74HC Series)
s Low input current: 1 µA maximum
s Fanout of 10 LS-TTL loads

Note 1: This configuration is nonstable; that is, it will not persist when pre-
set and clear inputs return to their inactive (HIGH) level.
