PI74FCT273T
(25
Ω Series) P174FCT2273T
Octal D Flip-Flop with Master Reset
Product Description
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 0.6/0.8 micron CMOS
technology, achieving industry leading speed grades. All
PI74FCT2XXX devices have a built-in 25-ohm series resistor on
all outputs to reduce noise because of reflections, thus eliminating
the need for an external terminating resistor.
The PI74FCT273T and PI74FCT2273T is an 8-bit wide octal
designed with eight edge-triggered D-type flip-flops with individual
D inputs and O outputs. The common buffered Clock (CP) and
Master Reset (MR) load and resets (clear) all flip-flops
simultaneously. The register is fully edge-triggered. The D input
state, one setup time before the LOW-to-HIGH clock transition, is
transferred to the corresponding flip-flop's O output. All outputs
will be forced LOW independently of Clock or Data inputs by a
LOW voltage level on the MR input.
Device models available upon request.
