Product Description
Pericom Semiconductor鈥檚 PI3B series of logic circuits are produced
using the Company鈥檚 advanced submicron CMOS technology,
achieving industry-leading performance.
The PI3B4011 is a 3.3V, 10- to 40-bit demultiplexing/multiplexing bus
switch. It is intended for multiple data or address muxing. Industry
leading advantages include a propagation delay of 225ps, resulting
from the 20-ohm channel resistance, and low I/O capacitance. The
A-port multiplexes to one of four or all outputs allowing a complete
bank of 10 bits to switch. The switch is bidirectional.
