PI49FCT32806 3.3V, 2 x 1:5 CMOS Clock Driver Features Description Low output skew: <270ps Pericom Semiconductors PI49FCT32806 are inverting drivers. The Switching frequency of 133 MHz outputs are configured into 2 groups of 1-in, 5-out with independent output enable. Group B has an extra MON output. Excellent output Fast output rise/fall time <1.5ns signals to power and ground ratio minimize power and ground noise, Low propagation delay <3.0ns and also improves output performance. Low input capacitance <6.0pF PI49FCT32806 integrate series damping resistors on all outputs. Balanced CMOS outputs Industrial Temperature: 40C to +85C 3.3V 10% operation Packaging (Pb-free & Green available): 20-pin 150-mil wide QSOP (Q) Block Diagram Pin Configuration 1 20 VCCA VCCB OEA OA0 2 19 OB0 5 OA1 OB1 3 18 INA OA04 OA2 OB2 4 17 20-Pin GNDA GNDB 5 16 Q,S 5 OA3 OB3 INB 6 15 OB04 OA4 OB4 7 14 OEB GNDQ MON 8 13 OEA OEB 9 12 MON INA INB 10 11 (1) Pin Description Truth Table Inputs Outputs Pin Name Description OEA, OEB INA, INB OAN, OBN MON OEA, OEB Hi-Z State Output Enable Inputs (Active LOW) LL H H INA, INB Clock Inputs LH L L OAN, OBN Clock Outputs HL Z H MON Monitor Output HH Z L GND Ground Note: VCC Power 1.
