3.3V Fast CMOS

Buffer/Clock Driver

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.

Features

• 3.3Vversionof 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: –40°C to 85°C

• Packaging (Pb-free & Green available):

– 16-pin 300-mil wide plastic SOIC (S)
