Product Description

Pericom Semiconductor’s PI74FCT series of logic circuits are

produced in the Company’s advanced 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.

The PI74FCT827/828T and the PI74FCT2827/2828T are 10-bit

wide bus drivers providing high-performance bus interface

buffering for wide address/data paths or buses carrying parity. The

10-bit buffers have NAND-ed output enables for maximum control

flexibility. They are designed for high-capacitance load drive

capability, while providing low-capacitance bus loading at both

inputs and outputs. The PI74FCT827/2827T is a non-inverting of

the PI74FCT828/2828T.

Device models available upon request.
