Description
Pericom Semiconductor’s PI3B16245 is a 3.3 volt, hot-insertion, 16-
bit, 2-port bus switch that 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. The bus switch creates no
additional propagation delay or additional ground bounce noise.
