Product Description
2
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.
3 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
4 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.
5 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.
