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 PI49FCT3805D 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.
