PI49FCT3805/PI49FCT3806 3.3V Fast CMOS Buffer/Clock Driver Features Description II3.3V 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 driver designed with two independent groups of buffers. These buffers have 3-state Output Enable inputs (active LOW) with a 1-in, 5-out configuration per group. Each clock driver consist of two banks of drivers, driving five outputs each from a standard TTL compatible CMOS input. IIExtremely low output skew: 0.5ns IIMonitor ouput pin IIClock busing wih 3-state control IITTL input and CMOS output compatible IIIndustrial operation at -40C to 85C IIExtremely low static power (1mW, typ.)
