Description:
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.
