MC74HC174A
Hex D Flip-Flop with
Common Clock and Reset
HighâPerformance SiliconâGate CMOS
The MC74HC174A is identical in pinout to the LS174. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
This device consists of six D flipâflops with common Clock and
Reset inputs. Each flipâflop is loaded with a lowâtoâhigh transition of
the Clock input. Reset is asynchronous and activeâlow.
⢠Output Drive Capability: 10 LSTTL Loads
⢠TTL NMOS Compatible Input Levels
⢠Outputs Directly Interface to CMOS, NMOS, and TTL
⢠Operating Voltage Range: 4.5 to 5.5 V
⢠Low Input Current: 1.0 µA
⢠In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
⢠Chip Complexity: 162 FETs or 40.5 Equivalent Gates
