TECHNICAL DATA
IN74HC175A
Quad D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
The IN74HC175A is identical in pinout to the LS/ALS175. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
This device consists of four D flip-flops with common Reset and
Clock inputs, and separate D inputs. Reset (active-low) is asynchronous
and occurs when a low level is applied to the Reset input. Information at a
D input is transferred to the corresponding Q output on the next positive-
going edge of the Clock input.
•
Outputs Directly Interface to CMOS, NMOS, and TTL
•
Operating Voltage Range: 2.0 to 6.0 V
•
Low Input Current: 1.0

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or
V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
