Description
Pericom Semiconductor’s PI5C3244 features a set of eight bus
switches which is pinout and function compatible with the PI74F-
CT244T, 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.
