MC74HC174A
Hex D Flip-Flop with
Common Clock and Reset
High–Performance Silicon–Gate CMOS
The MC74HC174A is identical in pinout to the LS174. The device
inputs are compatible with standard CMOS outputs; with pull–up
resistors, they are compatible with LSTTL outputs.
This device consists of six D flip–flops with common Clock and
Reset inputs. Each flip–flop is loaded with a low–to–high transition of
the Clock input. Reset is asynchronous and active–low.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1.0 mA
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 162 FETs or 40.5 Equivalent Gates
