Description
Pericom Semiconductor聮s PI49FCT series of logic circuits are
produced using the Company聮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 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.
