Extremely low output skew: 0.5ns Monitor output pin Clock busing with Hi-Z state control TTL input and CMOS output compatible Extremely low static power (1mW, typ.) Hysteresis on all inputs Packages available: 20-pin 209 mil wide SSOP (H) 20-pin 300 mil wide SOIC (S) 20-pin 150 mil wide QSOP (Q) Device models available on request Industrial Operation to +85C

Pericom Semiconductors PI49FCT series of logic circuits are produced using the Companys advanced 0.8 micron CMOS technology, achieving industry leading speed grades. The PI49FCT805T and PI49FCT2805T are non-inverting clock drivers. The is an inverting clock driver designed with two independent groups of buffers that have Hi-Z state Output Enable inputs (active LOW) with 1-in, 5-out configuration per group. Each clock driver consists of two banks of drivers, driving five outputs each from a standard TTL-compatible CMOS input. The PI49FCT2805T also features a 25-ohm on-chip resistor for lower noise.
