Pericom Semiconductor’s PI74LCX series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS technology
achieving high speed while maintaining low power operation.
The PI74LCX541 is an 8-bit 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. This device offers a
flow-through organization for ease of board layout.
The PI74LCX541 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.
