Description

Pericom Semiconductor’s PI74LPT244 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.

The PI74LPT244 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.
