... Block Diagram 06-0181 Fast CMOS 3.3V 8-Bit 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 ...
