Product Description
Pericom Semiconductors PI74LCX series of logic circuits are
produced using the Companys advanced 0.6 micron CMOS
technology achieving high speed while maintaining low power
operation.
The 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.
