Level Translators

This level translator takes active high input (sourcing) type input and gives an active low (sinking)/active high (sourcing) open collector output. It draws minimum current from the input and gives comparatively high sinking/sourcing currents (250mA). Four such drivers are provided in a module and a free wheeling diode is also provided to the output common from each output. This is useful for driving inductive loads. A zener is provided in series with each input. This ensures a ‘must cross’ voltage for inputs which enhances the noise immunity of the unit. This unit is useful in following applications:

  • Converting active high output (sourcing) to active low
  • Driving relatively higher loads from low power outputs.
  • Interfacing between different voltage levels.
