DESCRIPTION
Pericom Semiconductor’s PI74FCT series of logic circuits are produced in the Company’s advanced 0.6 micron CMOS technology, achieving industry leading speed grades. All PI74FCT2XXX devices have a built-in 25Ω series resistor on all outputs to reduce noise owing to reflections, thus eliminating an external terminating resistor. Data is preloaded or the counters count on the rising edge of the clock. Count enable inputs and terminal count outputs allow these counters to be cascaded without loss of speed.
