HIGH SPEED CMOS DUAL 4-INPUT MULTIPLEXER

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

resulting from reflections, thus eliminating the need for an external

terminating resistor.

The PI74FCT153T/253T and PI74FCT2153T/2253T are high-

speed dual 4-input multiplexers. The PI74FCT153T/2153T has

TTL outputs, while the PI74FCT253T/2253T has 3-state outputs.

The output buffers are designed with a power-off disable allowing

“live insertion” of boards when used as backplane drivers.
