  • Three unidirectional channels with both non-inverting and inverting push-pull outputs
  • Suitable for use as a non-inverting buffer
  • Suitable for use as an inverting buffer
  • Suitable for use as a logic voltage down-converter
  • LEDs provide visual indication for power and all outputs
  • Includes provision for user to easily customize to accommodate higher input voltages or open-collector/drain signals
  • Typical application: convert 12V gear-tooth or wheel-speed sensor signal to 3.3V for FPGA / DAQ card
  • Mounting Options: Rubber Feet, Panel, or DIN Rail


General Description

The BUFDNI103 provides 3 unidirectional channels that may each be used as a non-inverting buffer or inverting buffer. It is ideally suited for converting from higher-voltage logic down to lower-voltage logic (e.g., 5V logic --> 3.3V logic). The output logic voltage is determined by the supply voltage that is applied (from 2.0V to 6.0V).

Extra input-side terminal block positions and solder pads are included to allow the user to easily add pull-up resistors for interfacing to open-collector / open-drain outputs (if needed), and also to allow the user to easily implement a resistor divider for interfacing to signals that are higher than the allowed maximum value.

This board includes terminal blocks to provide convenient access to the signals.

Applications

  • Interface between gear tooth sensor and FPGA / DAQ card
  • Interface between wheel speed sensor and FPGA / DAQ card
  • Converting high logic voltage signals down to 3.3V or 5V logic signals
  • General-purpose logic buffering or logic inversion


In this context, other names for buffers (or terms associated with buffers) are "signal amplifier," "logic level shifter," or "logic voltage translator."

Mounting Options

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
