Notes: 1. Type Definitions

  • PWR: power
  • GND: ground
  • I: input
  • O: output
  • SE: single ended signal 2. It is recommended that all Power Supply pins have a decoupling capacitor attached (0.1 μF minimum). 3. When CR coin cell battery is used, place a 301 Ω resistor between the coin cell and the decoupling capacitor to meet the UL safety requirement.
