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 DS9637ASC. All typicals are given for VCC = 5V and TA = 25˚C. 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 6:VDIFF (Differential Input Voltage)= (VI+ )−( VI−). VCM (Common Mode Input Voltage)= VI+o rVI−. Note 7: 500Ω ±1% in series with inputs. Note 8:The input not under test is tied to ground.
