PI49FCT805T
PI49FCT2805T
Fast CMOS Clock Driver/Buffer
Features Description
Extremely low output skew: 0.5ns
Pericom Semiconductor s PI49FCT805T and PI49FCT2805T
Monitor output pin are non-inverting clock drivers. Each clock driver consists of
two banks of drivers, driving five outputs each from a standard
Clock busing with Hi-Z state control
TTL-compatible CMOS input.
TTL input and CMOS output compatible
The PI49FCT2805T features a 25-Ohm on-chip resistor for
Extremely low static power (1mW, typ.)
lower noise.
Hysteresis on all inputs
