PI49FCT3805D/E 3.3V, 2 x 1:5 CMOS Clock Driver Features • • • • • • • • • Description Low output skew: <200ps Switching frequency up to 166 MHz Fast output rise/fall time: <1.0ns Low propagation delay: <2.5ns Low input capacitance: <6.0pF Balanced CMOS outputs Industrial Temperature: –40°C to +85°C 3.3V ±10% operation, 5V Input Tolerant 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) – 20-pin 173-mil wide TSSOP (L) Pericom Semiconductor’s PI49FCT3805D/E is composed of non-inverting drivers. The outputs are configured into 2 groups of one-in, five-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.
