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.
