Product Description:

ProductFeatures:

Pericom Semiconductor’s PI74FCT series of logic circuits are

produced in the Company’s advanced 0.6/0.8 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 because of reflections, thus eliminating

the need for an external terminating resistor.

• PI74FCT646T/648T/651T/652T/2646T/2652Tispincompatible

with bipolar FAST™ 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

• Extremelylowstaticpower

• Hysteresis on all inputs

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

• Packagesavailable:

– 24-pin300milwideplasticDIP(P)

– 24-pin150milwideplasticQSOP(Q)

– 24-pin150milwideplasticTQSOP(R)

– 24-pin300milwideplasticSOIC(S)

• Device models available upon request

The PI74FCT646T/648T/651T/652T and PI74FCT2646T/2652T

are designed with a bus transceiver with 3-state D-type flip-flops

and control circuitry arranged for multiplexed transmission of data

directlyfromthedatabusorfromtheinternalstorageregisters. The

PI74FCT651/652T/2652TutilizeGABandGBAsignalstocontrol

the transceiver functions. The PI74FCT646/2646T/648T utilize

the enable control (G) and direction pins (DIR) to control the

transceiver functions. SAB and SBA control pins are used to select

either real-time or stored data transfer. The circuitry used for select

control will eliminate the typical decoding glitch that occurs in a

multiplexerduringthetransitionbetweenreal-timeandstoreddata.

A low input level selects real-time data and a high selects stored

data.

The PI74FCT646T is a non-inverting option of the PI74FCT648T.

The PI74FCT652T is a non-inverting option of the PI74FCT651T.
