Low-voltage analog switches ease system design
The digital control pins of Nexperia’s NMUX130x series of 1.5-V to 5.5-V analog switches are compatible with 1.8-V logic thresholds across the entire supply range. Since the control pins operate independently of the VCC range, no additional components are required for voltage translation. The series includes AEC-Q100 qualified variants for automotive use, as well as general-purpose versions to address consumer and industrial applications.
The NMUX1308 is an 8-channel multiplexer/demultiplexer, whereas the NMUX1309 offers a dual 4-channel multiplexer/demultiplexer. All analog signal pins are bidirectional. Integrated injection-current control limits output voltage shifts on the active channel to under 5 mV when an overvoltage event happens on disabled signal channels.
IOFF protection circuitry on digital control pins and analog switch pins enhances overall system safety. Standard devices operate over a temperature range of -40°C to +85°C. Automotive qualified parts operate over a temperature range of -40°C to +125°C. Packaging options for the switches include both leaded and leadless options.
