Pericom Semiconductor’s PI74LCX16244 is a 16-bit buffer/line
driver designed for driving 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 PI74LCX16244 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.
