Description
Pericom Semiconductor’s PI3B16244 is a 16-bit, 4-port bus switch
that is pin compatible with the 74 series 16244 16-bit driver. Four
enable signals (nBE) turn the switch on similar to the enable signals
of the 16244. The bus switch creates no additional propagation
delay or ground bounce noise.
