Notes: 1. External circuitry should be designed to ensure the ZCD sink current pulled from the internal clamp diode when it
is forward biased does not exceed specification.
2. Specifications guaranteed by design and are characterized and correlated using statistical process methods.
3. STBY is designed to be driven by an open collector. The input is internally pulled up with a 600k
 resistor.
4. For test purposes, load capacitance (C
L
) is 1nF and is connected as shown in the following diagram.
