PI49FCT32805 3.3V, 2 x 1:5 CMOS Clock Driver Features * * * * * * * * * Low output skew: <270ps Switching frequency of 133 MHz Fast output rise/fall time <1.5ns Low propagation delay <3.0ns Low input capacitance <6.0pF Balanced CMOS outputs Industrial Temperature: -40C to +85C 3.3V 10% operation Packaging: (Pb-free & Green Available) - 20-pin 300-mil wide SOIC (S) - 20-pin 150-mil wide QSOP (Q) - 20-pin 209-mil wide SSOP (H) Description Pericom Semiconductor's PI49FCT32805 is a fast speed, low skew, fast slew rate, and low propagation delay for most computing and communication applications. The devices are non-inverting drivers. The outputs are configured into 2 groups of 1-in, 5-out with independent output enable. Group B has an extra MON output. Excellent output signals to power and ground ratio minimize power and ground noise, and also improves output performance. PI49FCT32805 integrate series damping resistors on all outputs.
