Pericom Semiconductor’s PI49FCT805T and PI49FCT2805T are
non-inverting clock drivers. Each clock driver consists of two
banks of drivers, driving five outputs each from a standard TTLcompatible CMOS input.
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
Device models available on request
Industrial Operation at -40ºC to +85ºC
Packaging (Pb-free & Green available):
– 20-pin 209-mil wide SSOP (H)
– 20-pin 300-mil wide SOIC (S)
– 20-pin 150-mil wide QSOP (Q)
The PI49FCT2805T features a 25-ohm on-chip resistor for lower
noise.
