Description
Pericom Semiconductor’s PI49FCT32805 is a fast speed, low skew,
fast slew rate, and low propagation delay for most computing and
communication applications.
The devices are non-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.
PI49FCT32805 integrate series damping resistors on all outputs.
