These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. 1. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

Recommended Circuit Configuration The power supply circuit of the optimal performance on the application of a system should refer to Fig. 2. VDD decoupling is important to both reduce Jitter and EMI radiation. The C1 decoupling capacitor should be placed as close to the VDD pin as possible, otherwise the increased trace inductance will negate its decoupling capability. The C2 decoupling capacitor shown should be a tantalum type.
