Description
Pericom Semiconductor’s PI49FCT3805D/E 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.
