Notes: 1. Specifications guaranteed by design and are characterized and correlated using statistical process methods.
2. STBY is designed to be driven by an open collector. The input is internally pulled up with a 600kï resistor.
3. For test purposes, load capacitance (CL) is 1nF and is connected as shown in the following diagram.
