DESCRIPTION

The B5S162861 is an advanced high-speed
CMOS 20-BIT TWO PORT BUS SWITCH
fabricated with sub-micron silico n gate and
double-layer metal wiring C
It is ideal for 4V to 5.5V V

ultra-low power and low noise applications,
typically notebook and docking station.
Any nG
SWITCHES. Output Enable inputs (nG

output control governs two 10-bit BUS

)tied
together gives full 20-bit operations. When nG
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
25Ω 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.
