PI74LCX240
Fast CMOS 3.3V 8-Bit Buffer/Line Driver
Product Description
Pericom Semiconductor’s PI74LCX series of logic circuits are
produced using the Company’s advanced 0.6 micron CMOS
technology achieving high speed while maintaining low power
operation.
The PI74LCX240 is an 8-bit inverting buffer/line driver designed for
driving high capacitive memory loads. With its balanced-drive
characteristics, this high-speed, low power device provides lower
ground bounce, transmission line matching of signals, fewer line
reflections and lower EMI and RFI effects. This makes it ideal for
driving on-board buses and transmission lines.
The PI74LCX240 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.
