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 e n a b l e 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.
