MC74HC175A
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

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, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
