Fast CMOS 3.3V 8-Bit
Buffer/Line Driver
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.
