Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced 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 PI74FCT646T/648T/651T/652T and PI74FCT2646T/2652T
are designed with a bus transceiver with 3-state D-type flip-flops
and control circuitry arranged for multiplexed transmission of data
directly from the data bus or from the internal storage registers. The
PI74FCT651/652T/2652T utilize GAB and GBA signals to control
the transceiver functions. The PI74FCT646/2646T/648T utilize
the enable control (G) and direction pins (DIR) to control the
transceiver functions. SAB and SBA control pins are used to select
either real-time or stored data transfer. The circuitry used for select
control will eliminate the typical decoding glitch that occurs in a
multiplexer during the transition between real-time and stored data.
A low input level selects real-time data and a high selects stored
data.
The PI74FCT646T is a non-inverting option of the PI74FCT648T.
The PI74FCT652T is a non-inverting option of the PI74FCT651T.
