DATASHEET 0.5Ω LOW VOLTAGE, SINGLE SPDT ANALOG SWITCH Description Features The IDTAS4624 low on-resistance (RON), low voltage, single-pole/double-throw (SPDT) analog switch operates from a single +1.8 V to +5.5 V supply. The IDTAS4624 features a 0.5Ω (max) RON for its NC switch and a 0.8Ω (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 input is 1.8 V logic-compatible with a +2.7 V to +3.3 V supply. • • • • • • • • • • • • • Applications • • • • • • • Speaker headset switching MP3 players Battery-operated equipment Audio and video signal routing PCMCIA cards Cellular phones Modems IDTAS4624 +1.8 V to +5.5 V single-supply operation Rail-to-rail signal handling 1.8 V logic compatibility RON match between channels: 0.06Ω (max) RON flatness over signal range: 0.15Ω (max) NC Switch RON: 0.5Ω max (+2.7 V Supply) NO Switch RON: 0.8Ω max (+2.7 V Supply) Low crosstalk: -68dB (100 kHz) High Off-isolation: -64dB (100 kHz) THD: 0.03% 50 nA (max) supply current Low leakage currents: 1 nA (max) at TA = +25°C 6-pin SOT-23 package Block Diagram IDT™ 0.5Ω LOW VOLTAGE, SINGLE SPDT ANALOG SWITCH 1 IDTAS4624 REV D 081209 IDTAS4624 0.5Ω LOW VOLTAGE, SINGLE SPDT ANALOG SWITCH ANALOG SWITCH Pin Assignment (SOT-23) Truth Table IN NO NC 0 OFF ON 1 ON OFF Note: Switches shown for logic “0” input.

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.
