74AC273 • 74ACT273
Octal D-Type Flip-Flop
General Description
The AC273 and ACT273 have eight edge-triggered D-type
flip-flops with individual D-type inputs and Q outputs. The
common buffered Clock (CP) and Master Reset (MR) input
load and reset (clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D-
type input, one setup time before the LOW-to-HIGH clock
transition, is transferred to the corresponding flip-flop’s Q
output.
All outputs will be forced LOW independently of Clock or
Data inputs by a LOW voltage level on the MR input. The
device is useful for applications where the true output only
is required and the Clock and Master Reset are common to
all storage elements.
