MM74HC175
Quad D-Type Flip-Flop With Clear
The 74HC logic family is functionally as well as pin-out
compatible with the standard 74LS logic family. All inputs
are protected from damage due to static discharge by inter-
nal diode clamps to VCC and ground.
General Description
The MM74HC175 high speed D-type flip-flop with comple-
mentary outputs utilizes advanced silicon-gate CMOS
technology to achieve the high noise immunity and low
power consumption of standard CMOS integrated circuits,
along with the ability to drive 10 LS-TTL loads.
Features
■ Typical propagation delay: 15 ns
Information at the D inputs of the MM74HC175 is trans-
ferred to the Q and Q outputs on the positive going edge of
the clock pulse. Both true and complement outputs from
each flip flop are externally available. All four flip-flops are
controlled by a common clock and a common CLEAR.
■ Wide operating supply voltage range: 2–6V
■ Low input current: 1 µA maximum
■ Low quiescent supply current: 80 µA maximum (74HC)
■ High output drive current: 4 mA minimum (74HC)
Clearing is accomplished by
a negative pulse at the
CLEAR input. All four Q outputs are cleared to a logical “0”
and all four Q outputs to a logical “1.”
