PI74FCT161T/163T

(25Ω Series) PI74FCT2161T/2163T

High Speed CMOS Synchronous

4-Bit Binary Counters

Product Features

Product Description

• PI74FCT161/163/2161/2163T are pin-compatible with

bipolar FAST^TMSeries at a higher speed and lower power

consumption

• 25Ωseries 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

Pericom Semiconductor’s PI74FCT series of logic circuits are

producedintheCompany’sadvanced0.6micronCMOStechnology,

achievingindustryleadingspeedgrades.AllPI74FCT2XXXdevices

have a built-in 25Ω 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.

Countenableinputsandterminalcountoutputsallowthesecounters

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.

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

• Packages available:

- 16-pin 150 mil wide plastic QSOP (Q)

- 16-pin 150 mil wide plastic SOIC (W)

- 16-pin 300 mil wide plastic SOIC (S)
