ProductDescription

Pericom Semiconductor’s PI3B series of logic circuits are produced

using the Company’s advanced submicron CMOS technology,

achieving industry-leading performance.

ThePI3B4010isa3.3V,10-to40-bitdemultiplexing/multiplexingbus

switch. It is intended for multiple data or address muxing. Industry

leading advantages include a propagation delay of 300ps, resulting

from the 35-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.

ProductFeatures

• Standard Operating Temperature: 0ºC to +70ºC

• Channel ON Capacitance: 15pF max.

• Fast switching time: 3ns max.

• Package options include:

- 64-ball Thin Fine Pitch Ball Grid Array (TFBGA)

Applications

• DDR DIMM bank switching
