Pinout

Left Side

  • VEE — Negative power supply (can be left unconnected)
  • VCC — Module power supply, 5 V
  • GND — Ground
  • Z — Common input/output signal
  • S0–S2 — Digital select inputs to choose one of the 8 analog channels
  • E — Enable pin (active low; when HIGH, switches are off)

Right Side

  • VEE — Negative power supply (can be left unconnected)
  • VCC — Module power supply, 5 V
  • GND — Ground
