PI49FCT3807 3.3V Fast CMOS Clock Driv er Features Description 3.3V version of PI49FCT807 Pericom Semiconductors PI49FCT3807 is a 3.3V 1-to-10 clock Ultra low skew: 0.35ns driver. This low skew clock driver features one input and ten outputs fanout. The large fanout from a single input line reduced loading Low Input Capacitance on input clock. TTL level outputs reduce noise levels on the part. Minimum duty cycle distortion Typical applications are clock and signal distributon 1:10 fanout High speed: 3.5ns propogation TTL input and CMOS output compatible VOH =3.3V (typical) VOL =0.3V (typical) 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) Pin Con guration Block Di a gram A 1 20 V B0 CC GND 2 19 B9 B0 3 18 B8 B1 V 4 17 GND CC B1 5 16 B7 B2 GND 6 15 V CC B3 B2 7 14 B6 V 8 13 GND CC B4 9 12 B3 B5 A GND 10 11 B4 B5 B6 Pin Description Pin Name Description B7 A Input B -B Outputs 0 9 B8 GND Ground V Power CC B9 PS7010F 11/16/09 09-0005 1PI49FCT3807 3.3V Fast CMOS Clock Driver Maximum Ratings (Above which the useful life may be impaired.
