The 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. 3.3V version of PI49FCT805/806 Extremely low output skew: 0.5ns Monitor ouput pin Clock busing wih 3-state control TTL inpu and CMOS output compatible Industrial operation at40C to 85C Extremely low static power (1mW, typ.)
