NOTES:

1. Transients exceeding these conditions may damage the product.

2. Maximum dissipation is determined by the operating ambient temperature and the thermal resistance, and absolute maximum ratings may

impact product reliability

3. IC is protected for ESD voltages up to 2000 V, human body model.
