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. PI49FCT32806 integrate series damping resistors on all outputs. 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: –40°C to +85°C 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) Block Diagram Pin Configuration VCCA OEA OA0 5 INA OA0–4 OA1 OA2 GNDA 5 INB OA3 OB0–4 OA4 OEB GNDQ OEA MON INA 20 19 18 17 16 15 14 13 12 11 VCCB OB0 OB1 OB2 GNDB OB3 OB4 MON OEB INB Truth Table(1) Pin Description Pin Name OEA, OEB INA, INB OAN, OBN MON GND VCC 1 2 3 4 20-Pin 5 H,Q,S 6 7 8 9 10 Inputs Description Hi-Z State Output Enable Inputs (Active LOW) Clock Inputs Clock Outputs Monitor Output Ground Power OEA, OEB L L H H INA, INB L H L H Outputs OAN, OBN MON H H L L Z H Z L Note: 1.
