PI5C3244 8-Bit/ 2-Port Switch

Pericom Semiconductor’s PI5C3244 features a set of eight bus switches which is pinout and function compatible with the PI74FCT244T, 74F244, and 74ALS/AS/LS 244 8-bit drivers. Two enable signals (BEn) turn the switches on similar to the enable signals of the 244. The bus switch creates no additional propagation delay or ground bounce noise. Block Diagram BE.
