The B5S162862 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 four 5-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 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.
