IN74ACT174

1

High-Speed Silicon-Gate CMOS

The IN74ACT174 is identical in pinout to the LS/ALS174,

HC/HCT174. The IN74ACT174 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.

• 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; 0.1 µA @ 25°C

• Outputs Source/Sink 24 mA
