MC74AC174 Datasheet, PDF (1/9 Pages) ON Semiconductor – Hex D Flip−Flop with Master Reset

MC74AC174, MC74ACT174
Hex D Flip−Flop
with Master Reset
The MC74AC174/74ACT174 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 during the
LOW−to−HIGH clock transition. The device has a Master Reset to
simultaneously clear all flip−flops.
• Outputs Source/Sink 24 mA
• ′ACT174 Has TTL Compatible Inputs
