74LPT244

PI74LPT244 Fast CMOS 3.3V 8-Bit Buffer/Line Driver Features Compatible with LCX™ and LVT™ families of products Supports 5V Tolerant Mixed Signal Mode Operation – Input can be 3V or 5V – Output can be 3V or connected to 5V bus Advanced Low Power CMOS Operation www.DataSheet4U.com Excellent output drive capability: Balanced drives (24mA sink and source) Low ground bounce outputs Hysteresis on all inputs Industrial operating temperature range: –40°C to +85°C Packages (Pb-free & Green available): – 20-pin 173-mil wide plastic TSSOP (L) – 20-pin 150-mil wide plastic QSOP (Q) – 20-pin 300-mil wide plastic SOIC (S) – 20-pin 209-mil wide plastic SSOP (H) 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. The PI74LPT244 can be driven from either 3.3V or 5.0V devices allowing this device to be used as a translator in a mixed 3.3/5.0V system.
