PI74FCT3244 Datasheet | Pericom Semiconductor

Features Advanced Low Power CMOS operation patible with LVC class of products patible with industry standard octal pinouts Excellent output drive capability: Balanced Drives (24m A sink and source) .. - Can serve as a 5V to 3V translator - Inputs can be driven by 3.3 V or 5V devices - Low ground bounce outputs - Hysteresis on all inputs - Industrial operating temperature range: - 40°C to +85°C - Packaging (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) - - - - 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.
