Description

Pericom Semiconductor’s PI3B series of logic circuits are pro-

duced using the Company’s advanced sub-micron CMOS tech-

nology, 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.
