DATASHEET
0.5 OHM, DUAL SPDT ANALOG SWITCH Description
The IDTAS4684 low on-resistance (RON), low voltage, dual single-pole/double-throw (SPDT) analog switch operates from a single +1.8 V to +5.5 V supply. The IDTAS4684 features a 0.5 (max) RON for its NC switch and a 0.8 (max) RON for its NO switch at a +2.7 V supply. It also features break-before-make switching action (2 ns) with tON = 50 ns and tOFF = 40 ns at +3 V. The digital logic inputs are 1.8 V logic-compatible with a +2.7 V to +3.3 V supply. Comes in 3 x 3 DFN, or 12-bump CSP packages.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the IDTAS4684. 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.

Note 3
+25C TMIN to TMAX
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 +25C only and guaranteed by design and correlation at the full hot-rated temperature. 3. Guaranteed by design. 4. RON = 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.
