Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices

should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.

Note 3: Unless otherwise specified Min/Max limits apply across the −55˚C to +125˚C temperature range for DS9637AM and across the 0˚C to +70˚C range for the

Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground unless otherwise specified.

Note 5: Only one output at a time should be shorted.

Note 7: 500

Note 8: The input not under test is tied to ground.
