DESCRIPTION
The B5S162861 is an advanced high-speed
CMOS 20-BIT TWO PORT BUS SWITCH
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS tecnology.
It is ideal for 4V to 5.5V VCC operations 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
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.

Absolute Maximum Rating are those value beyond which damage to the device may occour. Functional operation under these condition is
not implied
1) IO absolute maximum rating must be observed
2) VO < GND, VO > VCC
3) Not more than one output should be tested at one time. Duration of the test should not exceed one second.
