Fast CMOS
Buffer/Clock Driver
Product Features
• Low output skew: 0.8ns
• Clock busing with Hi-Z state control
• TTL input and output levels, reducing problematic
“ground bounce”
• High output drive, I_OL = 64mA
• Extremely low static power (1mW, typ.)
• Hysteresis on all inputs
• Packages available:
– 16-pin 300 mil wide plastic SOIC (S)
– 16-pin 150 mil wide QSOP (Q)
Product Description
Pericom Semiconductor’s PI49FCT series of logic circuits are
produced using the Company’s advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
The PI49FCT804T 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.
