ProductDescription

CommonFeatures

Pericom Semiconductors PI74FCT series of logic circuits are pro-

duced in the Companys advanced 0.8 micron CMOS technology,

achieving industry leading speed grades.

PI74FCT16511andPI74FCT162511arehigh-speed,low

power devices with high current drive.

Vcc=5V±10%

Hysteresis on all inputs

The PI74FCT16511T and PI74FCT162511T are high-speed, low-

power 16-bit registered/latched transceiver with parity which

combines D-type latches and D-type flip-flops to allow data flow in

transparent, latched or clocked modes. It has a parity generator/

checker in the A-to-B direction and a parity checker in the B-to-A

direction.Errorcheckingisdoneatthebytelevelwithseparateparity

bits for each byte. One error flag for each direction (A-to-B or B-to-

A) exists to indicate an error for either byte in either direction. The

parity error flags which are open drain outputs, can be tied together

and/or tied with flags from other devices to form a single error flag

orinterrupt.Todisabletheerrorflagduringcombinationaltransitions,

PI74FCT16511TFeatures

High output drive: I^OH= 32mA; IOL = 64mA

Power off disable outputs permit live insertion

Typical VOLP (Output Ground Bounce) < 1.0V

atVCC =5V,TA =25°C

The operation in A-to-B direction is controlled by LEAB, CLKAB

and OEAB control pins, and the operation in B-to-A direction is

controlledbyLEBA,CLKBAandOEBAcontrolpins. GEN/CHKis

used to select the operation of A-to-B direction, while B-to-A

direction is always in checking mode. The ODD/EVEN select is

commonbetweenthetwodirections. Independentoperationcanbe

achieved between the two directions by using the corresponding

controllinesexceptfortheODD/EVENcontrol.
