Product Description
Pericom Semiconductors PI74LPT series of logic circuits are pro-
duced using the Companys advanced 0.6 micron CMOS
technology, achieving industry leading speed grades.
The PI74LPT541 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 PI74LPT541, which can be driven from either 3.3V or 5.0V
devices, can be used as a translator in mixed 3.3/5.0V systems.
