Description
Pericom Semiconductor’s PI74LPT16244 is a 16-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 is designed with three-state
controls to operate in a Quad-Nibble, Dual-Byte, or a single
16-bit word mode.
The PI74LPT16244 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.
