Autosense Translators

NXB, NXS

Nexperia’s NXB and NXS autosense translators, offer bi-directional voltage level translation between two systems with wide supply voltages and excellent performance in pin-to-pin compatible packages with industry-standard footprints. With auto-direction sensing, no external direction pin is required which eliminates the need of GPIOs from controllers.

  • NXS (switched)    –    Drives open-drain topology for applications such as  I2C 
  • NXB (Buffered)    –    Drives push-pull topology for applications with low capacitance high impedance load such as SPI
     

NXS

  • One pass transistor per channel – switch base
  • Additional one-shot circuit for edge rate acceleration
  • Internal pull-up resistor (10kΩ) connected to VCCA, VCCB 
  • Intended for push-pull and open-drain interfaces I2C
     

Features and benefits
