ONSEMI MC74AC174

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

MC74AC174 MC74ACT174
FUNCTIONAL DESCRIPTION
The MC74AC174/74ACT174 consists of six edge-triggered D
flip-flops with individual D inputs and Q outputs. The Clock
(CP) and Master Reset (MR) are common to all flip-flops. Each
D input’s state is transferred to the corresponding flip-flop’s
output following the LOW-to-HIGH Clock (CP) transition. A
LOW input to the Master Reset (MR) will force all outputs LOW
independent of Clock or Data inputs. The MC74AC174/
74ACT174 is useful for applications where the true output only
is required and the Clock and Master Reset are common to all
storage elements.
