They are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation. Note 3: Unless otherwise specified min/max limits apply across the 0˚C to +70˚C range for the DS3487. All typicals are given for VCC = 5V and TA = 25˚C. Note 4:All currents into device pins are positive, all currents out of device pins as negative. All voltages are referenced to ground unless otherwise specified. Note 5:Only one output at a time should be shorted. Note 6: Symbols and definitions correspond to EIA RS-422, where applicable. www.national.com 2
