leteDESCRIPTION
oThe B5S16862 is an advanced high-speed CMOS
s20-BIT TWO PORT BUS SWITCH fabricated with
bsub-micron silicon gate and double-layer metal
Owiring C2MOS tecnology.
-It is ideal for 4V to 5.5V VCC operations and
t(s)ultra-low power and low noise applications,
typically notebook and docking station.
cAny nG output control governs four 5-bit BUS
uSWITCHES. Output Enable inputs (nG) tied
dtogether gives full 20-bit operations. When nG is
roLOW, the switches are on. When nG is HIGH, the
Pswitches are in high impedance state.
It has ultra high-speed performance at 5V near
tezero delay with low ON resistance.
leAll inputs and outputs are equipped with protec-
otion circuits against static discharge, giving them
Obs2KV 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.
