3.3V Fast CMOS Buffer/Clock Driver
Features
* * * * * * * * * 3.3V version of PI49FCT804T Low output skew: 0.7ns Clock busing with Hi-Z state control TTL input and output levels, reducing problematic "ground bounce" Extremely low static power (1mW, typical) Hysteresis on all inputs ESD protection exceeds 2000V Industrial Operation: -40C to 85C Packaging (Pb-free & Green available): - 16-pin 300-mil wide plastic SOIC (S)
Description
Pericom Semiconductor's PI49FCT3804 is a non-inverting clock driver designed with two independent groups of buffers. These buffers have Hi-Z state Output Enable inputs (active LOW) with a 1-in, 4-out configuration per group. Each clock driver consists of two banks of drivers, driving four outputs each from a standard TTL compatible CMOS input.
