TECHNICAL DATA
IN74HC174A
Hex D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
The IN74HC174A is identical in pinout to the LS/ALS174. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL 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.
