This Module is currently available.

Discrete resistor-transistor XNOR/XOR/NOT logic gate

  • directly modelled on RTL digital logic gate designs pioneered in the 1950s used in computing equipment throughout the 50s and 60s.
  • can be used as audio waveshaper/distortion.
  • The XNOR/XOR/NOT module can be patched as:
    two NOT gates and one 2-input XOR gate,
    one NOT gate, one 2-input XOR gate and one 2-input XNOR/XOR gate,
    two 2-input XNOR/XOR gates, or,
    one NOT gate and one 3-input XNOR/XOR gate.
  • All analogue circuitry.
  • slim 4HP footprint.
  • compact 50mm Depth (with power cable attached).
  • low power draw: 28mA +12V / 0mA -12V / 0mA +5V.
  • Works for audio as well as CV.
  • Fast responding CV inputs allow up to audio rate operation.
  • The XOR out from gate one is normalized to input 1 on gate two.
  • The XOR out from gate two is normalized to the single input on gate three (NOT).
  • signal indicator LEDs on every input and output.
  • can accept input signal to +10V peak.
