Description
The PI74FCT3244 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, fewer line reflections
and lower EMI and RFI. This makes it ideal for driving on-board
buses and transmission lines.
The PI74FCT3244 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator.
