Product 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 25 series resistor on all outputs to reduce noise owing to reflections, thus eliminating an external terminating resistor. The PI74FCT161T and PI74FCT163 are high speed CMOS synchronous presettable 4-bit binary counters. The 161 has an asynchronous clear, the 163 has a clocked synchronous clear. 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. Preset inputs override count inputs, and clear inputs override both preset and count inputs. All inputs have clamp diodes for undershoot noise suppression. All outputs have ground bounce suppression.
