Quad D Flip-Flop with
Common Clock and Reset
High–Performance Silicon–Gate CMOS
The MC74HC175A is identical in pinout to the LS175. The device inputs
are compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL 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.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity 166 FETs or 41.5 Equivalent Gates
