Description
Pericom Semiconductor’s PI3B series of logic circuits are produced
using the Company’s advanced sub-micron CMOS technology,
achieving industry leading performance.
The PI3B3244 features a set of 3.3V 8-bit bus switches, which is
pinout and function compatible with the P74FCT244T, 74F244, and
74ALS/AS/LS2448-bit drivers. Two enable signals (BEn) turn the
switches on similar to the enable signals of the 244. The bus switch
create no additional propagation delay or ground bounce noise.
