Product Description

Pericom Semiconductor’s PI74LCX series of logic circuits are

produced using the Company’s advanced 0.6 micron CMOS

technology, achieving industry leading speed grades.

The PI74LCX16827 is a 20-bit wide bus driver designed to provide

buffering and high-performance bus interfacing for wide data/

address paths or busses with parity. Two pairs of nanded output

enable controls allow the device to be operated as two

10-bit buffers or as one 20-bit buffer. Signal pins are arranged in a

flow-through organization for ease of layout and hysteresis is

designed into all inputs to improve noise margin.

The PI74LCX16827 can be driven from either 3.3V or 5.0V devices

allowing this device to be used as a translator in a mixed

3.3V/5.0V system.
