SL74HC175
Quad D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
The SL74HC175 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 µA
• High Noise Immunity Characteristic of CMOS Devices
