SEMICONDUCTOR TECHNICAL DATA
Hex D Flip-Flop with
Common Clock and Reset
with LSTTL Compatible Inputs
High–Performance Silicon–Gate CMOS
The MC74HCT174A is identical in pinout to the LS174. This device may
be used as a level converter for interfacing TTL or NMOS outputs to High
Speed CMOS inputs.
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
• 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: 178 FETs or 44.5 Equivalent Gates
