Notes:
1. Exceeding the Absolute Maximum ratings may damage the device.
2. The device is not guaranteed to operate beyond the Maximum Operating ratings.
3. Devices are inherently ESD sensitive, handling precautions are required. Human body model rating: 1.5KΩ in series with
100pF.
4. Specification in BOLD indicate an ambient temperature range of -40°C to +85°C. These specifications are guaranteed
by design.
