Series)PI74FCT2157T/2257T
QUAD 2-INPUT MULTIPLEXER
(25
Series)PI74FCT2157T/2257T
Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 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 PI74FCT157T/257T and PI74FCT2157T/2257T are high-
speed quad 2-input multiplexers. The common select input can be
used to select four bits of data from two sources. The four buffered
outputs present the selected data in the true (non-inverting) form.
The PI74FCT157T/2157T has a common, active-LOW, Enable
input (E). When E is inactive, all four outputs are held LOW. The
PI74FCT157T/2157T can generate any four of the 16 different
funtions of two variables with one common variable. The
PI74FCT157T/2157T can be used as a function generator or to
move data from two different groups of registers to a common bus.
The PI74FCT257/2257T has a common Output Enable (OE) input.
When OE is HIGH, all outputs are switched to a high-impedance
state allowing the outputs to interface directly with bus-oriented
systems.
