DESCRIPTION

The B5S162861 is an advanced high-speed

CMOS

20-BIT

TWO

PORT

BUS

SWITCH

fabricated

with

sub-micron silicon gate and

ultra-low power and low noise applications,

typically notebook and docking station.

Any nG output control governs two 10-bit BUS

SWITCHES. Output Enable inputs (nG)tied

together gives full 20-bit operations. When nG is

LOW, the switches are on. When nG is HIGH, the

switches are in high impedance state.

It has ultra high-speed performance at 5V near

zero delay with low ON resistance and include

25

Ω series resistor to reduce noise resulting from

reflections, thus eliminating the need for an

external terminating resistor.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
