PI49FCT3805D

Description

Pericom Semiconductor’s PI49FCT series of logic circuits are

produced using the Company’s advanced submicron CMOS

technology to achieve fast speed, low skew, fast slew rate, and low

propagation delay for most computing and communication

applications.

The PI49FCT3805D is composed of non-inverting drivers. The

outputs are configured into 2 groups of one-in, five-out with

independent output enable. Group B has an extra MON output.

Excellent output signals to power and ground ratio minimize power

and ground noise and also improves output performance.

Features

• Low output skew: <270ps

• Switching frequency of 133 MHz

• Fast output rise/fall time: <1.5ns

• Low propagation delay: <3.0ns

• Low input capacitance: <6.0pF

• Balanced CMOS outputs

• IndustrialTemperature:–40°Cto+85°C

• 3.3V±10%operation

• Packagesavailable:

–20-pin300-milwideSOIC(S)

–20-pin150-milwideQSOP(Q)

–20-pin209-milwideSSOP(H)
