74ABT273
Octal D-Type Flip-Flop
General Description
The ABT273 has eight edge-triggered D-type flip-flops with
individual D inputs and Q outputs. The common buffered
Clock (CP) and Master Reset (MR) inputs load and reset
(clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D
input, one setup time before the LOW-to-HIGH clock transi-
tion, 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.
Features
s Eight edge-triggered D-type flip-flops
s Buffered common clock
s Buffered, asynchronous Master Reset
s See ABT377 for clock enable version
s See ABT373 for transparent latch version

s Output sink capability of 64 mA, source capability of
32 mA
s Guaranteed latchup protection
s High impedance glitch free bus loading during entire
power up and power down cycle
s Non-destructive hot insertion capability
s Disable time less than enable time to avoid bus conten-
tion
