Typical values are characteristic of the device and are the result of engineering evaluations. They are provided for information purposes only and are not part of the testing requirements. Specifications cover the operating temperature range TA = -40qC to +85qC. Also, unless otherwise specified, all testing is performed with VDD = 5VDC, logic low input voltage is 0VDC and logic high voltage is 5VDC. Absolute maximum electrical ratings are at 25qC. 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 conditions beyond those indicated in the operational sections of this data sheet is not implied. 4 PRELIMINARY R00E INTEGRATED CIRCUITS DIVISION CPC75282 PRELIMINARY 1.7 Switch Specifications 1.7.1 Break Switches, SW1 and SW2 Parameter Test Conditions Symbol Minimum Typical Maximum Unit ISW - - 1 PA 14.5 - - 31 10.5 - - 0.02 1.0 - - 320 60 - - V1 + 0.5 - - - 300 VSW1 (differential) = TLINE to TBAT VSW2 (differential) = RLINE to RBAT All-Off state.
