The HI-8195/HI-8196/HI-8197 are quad single-pole/single-throw (SPST) analog switches. The HI-8195 has four normally open (NO) switches, the HI-8196 has four normally closed (NC) switches and the HI-8197 has two NO and two NC switches. The devices are fabricated on a robust silicon-on-insulator (SOI) technology for latch-up free operation and maximum isolation, with off-state and power down leakage in the nano amp range. Switch nodes are open-circuit when power is off, making these devices ideal for data bus multiplexing or any other applications requiring very low leakage when no power is applied.

Switch operating range is +/-3V to +/-10V and is controlled by 3.3V or 5.0V logic. RON is 28 Ohm maximum, enabling these devices to be used for line driver isolation in a multi-drop ARINC 429 avionics bus. The devices are available in industrial -40^oC to +85^oC and extended -55^oC to +125^oC temperature ranges and come in 16 pin SOIC and 5mm x 5mm 16-pin QFN packages.
