IDT™ 0.5 OHM, DUAL SPDT ANALOG SWITCH 3 IDTAS4684A REV A 092507 Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the IDTAS4684A. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. All voltages referenced to ground.

IDT™ 0.5 OHM, DUAL SPDT ANALOG SWITCH 5 IDTAS4684A REV A 092507 Notes: 1. The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive value a maximum. 2. UCSP parts are 100% tested at +25°C only and guaranteed by design and correlation at the full hot-rated temperature. 3. Guaranteed by design. 4. R ON = RON(MAX) - RON(MIN), between NC1 and NC2 or between NO1 and NO2. 5. Flatness is defined as the difference between the maximum and minimum value of on resistance as measured over the specified analog signal ranges. 6. Off-isolation = 20log10 (VCOM / VCO), VCOM = output, VCO = input to off switch. Parameter Symbol Conditions T A Min. Typ. Max.
