PI74LCX16244 Fast CMOS 3.3V 16-Bit Buffer/Line Driver Features Functionally compatible with FCT3, LVT, and 74 series 16244 families of products 3-State outputs 5V Tolerant inputs and outputs 2.0V-3.6V VCC supply operation Balanced sink and source output drives (24mA) Low ground bounce outputs Power Down High Impedance inputs and outputs Supports live insertion ESD Protection exceeds 2000V, Human Body Model 200V, Machine Model Packages available: – 48-pin 240-mil wide plastic TSSOP (A) – 48-pin 300-mil wide plastic SSOP (V) Description 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.
