Absolute Maximum Ratings

Exceeding the Absolute Maximum ratings may damage the

device.

Note:

1. Devices are inherently ESD sensitive, handling precautions are

required. Human body model rating: 1.5k

Ω in series with 100pF.

Recommend Operating Ratings

The device is not guaranteed to operate beyond the Maximum

Operating Ratings.

Note:

2. The value of

Θ

value in any given application depends on the user’s specific board

design.

Electrical Characteristics

Note:

3. Specification in BOLD indicate an ambient temperature range of -40°C to +85°C. These specifications are guaranteed by design.
