Notes: 1. See the Detector Frequency Windows table on page 4 for detection/ rejection frequencies. www.clare.com M-984-02 Rev. 3 Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the opera- tional sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extend- ed period may degrade the device and effect its reliability. 2 Absolute Maximum Ratings DC Supply Voltage 7V Input Voltage on SIGIN V SS - 6.5V to VDD +0.3V Input Voltage on Any Pin V SS - 0.3 to VDD + 0.3V (except SIGIN) Storage Temperature Range -40°C to +150°C Operating Temperature Range -40°C to +85°C Lead Soldering Temperature 260°C for 5 seconds Note: Exceeding these ratings may permanently damage the device. |
