PI74FCT191T

(25Ω Series) PI74FCT2191T

High Speed CMOS Presettable Synchronous

4-Bit Binary Counters

Product Features

PI74FCT191/2191TispincompatiblewithbipolarFAST

Product Description

Pericom Semiconductors PI74FCT series of logic circuits are

produced in the Companys advanced 0.6 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 due to reflections, thus eliminating the

need for an external terminating resistor.

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)

Extremely low static power

Hysteresis on all inputs

The PI74FCT191T is a high speed CMOS 4-bit binary up/down

counter. It has a single clock with clock enable and up/down

control inputs and ripple carry output. The 191 has asynchronous

preload inputs which override the count inputs. All inputs have

clamp diodes for undershoot noise suppression. All outputs have

ground bounce suppression.

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