Hex D Flip-Flop with Master Reset
General Description
The ’AC/’ACT174 is a high-speed hex D flip-flop. The device
is used primarily as a 6-bit edge-triggered storage register.
The information on the D inputs is transferred to storage dur-
ing the LOW-to-HIGH clock transition. The device has a
Master Reset to simultaneously clear all flip-flops.
n Outputs source/sink 24 mA
