Fast CMOS

Buffer/Clock Driver

ProductDescription

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.

ThePI49FCT804Tisanon-invertingclockdriverdesignedwithtwo

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.

ProductFeatures

• Low output skew: 0.8ns

• Clock busing with Hi-Z state control

• TTL input and output levels, reducing problematic

“ground bounce”

• Extremely low static power (1mW, typ.)

• Hysteresis on all inputs

• Packagesavailable:

– 16-pin300milwideplasticSOIC(S)

– 16-pin150milwideQSOP(Q)
