Description

Pericom Semiconductor’s PI3B16245VE is a 3.3 volt, hot-insertion, 16- bit, 2-port bus switch. This switch is pin compatible with the 74 series 16245 16-bit transceiver. Two enable signals (nBE) turn the switches on similar to the enable signals of the 16245. This bus switch creates no additional propagation delay or additional ground bounce noise.
