Quad D Flip-Flop with

Common Clock and Reset

High-Speed Silicon-Gate CMOS

The IN74ACT175 is identical in pinout to the LS/ALS175,

HC/HCT175. The IN74ACT175 may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

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.

• 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
