DESCRIPTION
The B5S16861 is an advanced high-speed CMOS
20-BIT TWO PORT BUS SWITCH fabricated with
sub-micron silicon 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 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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
