Product Description:

• PI74FCT157/257/2157/2257Tispincompatiblewithbipolar

FAST™ Series at a higher speed and lower power

consumption

• 25Ω series resistor on all outputs (FCT2XXX only)

• TTL input and output levels

• Low ground bounce outputs (25Ω series only)

• Extremelylowstaticpower

• Hysteresis on all inputs

Pericom Semiconductor’s PI74FCT series of logic circuits are pro-

duced in the Company’s advanced 0.8 micron CMOS technology,

achievingindustryleadingspeedgrades.AllPI74FCT2XXXdevices

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.

• Industrial operating temperature range: –40°C to +85°C

• Packagesavailable:

– 16-pin150milwideplasticQSOP(Q)

– 16-pin300milwideplasticSOIC(S)

– 16-pin150milwideplasticSOIC(W)

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.
