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.
