TECHNICAL DATA
IN74ACT174
Hex D Flip-Flop with
Common Clock and Reset
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.
