Interface

Multi-switch detection interface (MSDI) for simplified switch monitoring

Optimize input-output monitoring and serialization in automotive and industrial systems

Monitor your multi-position analog and digital switches in automotive and industrial applications with our portfolio of integrated multi-switch detection interface (MSDI) devices. These products can include integrated wetting currents, reverse blocking and ESD protection to help enable smaller switch-contact monitoring solutions for applications such as body control modules.

Multi-switch detection interface devices

Fully integrated low-power switch and sensor interface devices to monitor multi-position analog and digital switches in automotive and industrial applications

Industrial serializers

High-voltage serializers for industrial I/Os that support up to 8 inputs with a single device, or can be cascaded for additional inputs in PC, PLC and other industrial systems
