PI49FCT32806

Description

Pericom Semiconductor’s PI49FCT32806 are inverting drivers. The

outputs are configured into 2 groups of 1-in, 5-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.

PI49FCT32806 integrate series damping resistors on all outputs.

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

• Industrial Temperature: –40°C to +85°C

• 3.3V±10%operation

• Packaging (Pb-free & Green available):
