Block Diagrams

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.

Notes:

1. Derate power dissipation linearly 2.50mW/°C above 25°C.

2. RMA flux is recommended.

3. Methanol or isopropyl alcohols are recommended as cleaning agents.

4. Soldering iron tip 1/16" (1.6mm) minimum from housing.
