PI49FCT3805/PI49FCT3806 3.3V Fast CMOS Buffer/Clock Driver Features Description Î 3.3V version of PI49FCT805/806 Pericom Semiconductor’s PI49FCT3805 is a 3.3V non-inverting clock driver and the PI49FCT3806 is a 3.3V inverting clock Î Extremely low output skew: 0.5ns driver designed with two independent groups of buffers. These Î Monitor ouput pin buffers have 3-state Output Enable inputs (active LOW) with a Î Clock busing wih 3-state control 1-in, 5-out configuration per group. Each clock driver consist of Î TTL input and CMOS output compatible two banks of drivers, driving five outputs each from a standard TTL compatible CMOS input. Î Industrial operation at –40°C to 85°C Î Extremely low static power (1mW, typ.) Î Hysteresis on all inputs Î Packaging (Pb-free & Green available): à 20-pin 150-mil wide QSOP (Q) à 20-pin 209-mil wide SSOP (H) PI49FCT3805 Block Diagram PI49FCT3806 Block Diagram OEA OEA 5 5 INA OA0-4 INA OA0-4 5 5 INB OB0-4 INB OB0-4 OEB OEB MON MON 11-0004 1 www.pericom.com PS7007L 07/23/10
