NOTE:

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 for 2000V, excepts pins 10 and 12, which are protected up to 500V.
