PI49FCT32805 3.3V, 2 x 1:5 CMOS Clock Driver Features Description Low output skew: <270ps Pericom Semiconductors PI49FCT32805 is a fast speed, low skew, Switching frequency of 133 MHz fast slew rate, and low propagation delay for most computing and communication applications. Fast output rise/fall time <1.5ns Low propagation delay <3.0ns The devices are non-inverting drivers. The outputs are configured into 2 groups of 1-in, 5-out with independent output enable. Group Low input capacitance <6.0pF B has an extra MON output. Excellent output signals to power and Balanced CMOS outputs ground ratio minimize power and ground noise, and also improves Industrial Temperature: 40C to +85C output performance. 3.3V 10% operation PI49FCT32805 integrate series damping resistors on all outputs.
