Description
Pericom Semiconductors PI49FCT series of logic circuits are
produced using the Companys advanced submicron CMOS
technology to achieve fast speed, low skew, fast slew rate, and low
propagation delay for most computing and communication
applications.
The PI49FCT32805 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.
