Product Description
Pericom Semiconductor’s PI74LPT series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74LPT16827 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 PI74LPT16827 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3/5.0V system.
