Except for “Operating Temperature Range” 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 +75˚C temperature range for the DS1489 and DS1489A. Note 4: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown as max or min on absolute value basis. Note 5: These specifications apply for response control pin = open. www.national.com 3 |
