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 θ_JA: 24-Pin TSSOP = 117°C/W
3. IC is protected for ESD voltages up to 2000 V, human body model.
