ProductDescription

PI74FCT543T/544/2543Tispincompatiblewithbipolar

FAST Series at a higher speed and lower power

consumption

Pericom Semiconductors PI74FCT series of logic circuits are

produced using the Companys advanced 0.8 micron CMOS

technology, achieving industry leading speed grades. All

PI74FCT2XXXdeviceshaveabuilt-in25ohmseriesresistoronall

outputs to reduce noise because of reflections, thus eliminating the

need for an external terminating resistor.

25Ω series resistor on all outputs

TTL input and output levels

Low ground bounce outputs

Extremely low static power

Hysteresis on all inputs

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

Packages available:
