PIN I/O(1) DESCRIPTION
NO. NAME
1 IN I Switch input.
2 GND — Device ground.
3 ON I Active high switch control input. Do not leave floating.
4 NC —

No connect. This pin is not internally connected. It is recommended to connect this pin to GND to prevent charge buildup; however, this pin can also be left open or tied to any voltage between GND and IN.
5 QOD O Quick Output Discharge pin. This pin can be utilized in one of three ways:
  • Placing an external resistor between VOUT and QOD
  • Tying QOD directly to VOUT and using the internal resistor value (RPD)
  • Disabling QOD by leaving pin floating
See the Fall Time (tFALL) and Quick Output Discharge (QOD) section for more information.
6 OUT O Switch output.
