Chapter 2 Electrical Specifications

2.1

Absolute Maximum Ratings

Note: Stresses at or above those listed could cause permanent damage to the device. This is a stress

rating only and functional operation of the device at any other condition above those indicated

in the operation sections of this specification is not implied. When powering this device from

laboratory or system power supplies, it is important that the Absolute Maximum Ratings not be

exceeded or device failure can result. Some power supplies exhibit voltage spikes on their

outputs when the AC power is switched on or off. In addition, voltage transients on the AC

power line may appear on the DC output. If this possibility exists, it is suggested that a clamp

circuit be used.

Note 2.1

For the 5V tolerant pins that have a pull-up resistor, the pull-up voltage must not exceed

3.6V when the device is unpowered.
