PI74FCT193T

(25Ω Series) PI74FCT2193T

High-Speed CMOS Presettable

Synchronous 4-Bit Binary Counters

Product Features

Product Description

• PI74FCT193/2193TispincompatiblewithbipolarFAST

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

Pericom Semiconductors PI74FCT series of logic circuits are

produced using 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.

• Hysteresis on all inputs

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

• Packages available:

The PI74FCT193 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 193 has asynchronous

preload inputs which override the count inputs. All inputs have

clamp diodes for undershoot noise suppression. All outputs have

ground bounce suppression.
