PI49FCT3805D
3.3V, 2 x 1:5 CMOS Clock Driver
Features Description
• Low output skew: <200ps Pericom Semiconductor’s PI49FCT3805D is composed of non-
• Switching frequency up to 166 MHz inverting drivers. The outputs are configured into 2 groups of
• Fast output rise/fall time: <1.0ns one-in, five-out with independent output enable. Group B has an
• Low propagation delay: <2.5ns extra MON output. Excellent output signals to power and ground
• Low input capacitance: <6.0pF ratio minimize power and ground noise and also improves output
performance.
• Balanced CMOS outputs
• Industrial Temperature: –40°C to +85°C
• 3.3V ±10% operation, 5V Input Tolerant
• Packaging (Pb-free & Green available):
– 20-pin 150-mil wide QSOP (Q)
– 20-pin 209-mil wide SSOP (H)
