Texas Instruments · Analog switch (SPDT) · SOT-23-6
Single-pole double-throw analog switch that routes one common line (COM) to either of two throws (NO, NC) under a logic input, in a SOT-23-6. A 1 ohm on-resistance and low charge injection pass audio and other analog signals cleanly, and it runs from a single 1.65 to 5.5 V rail. The switch is break-before-make, so the two throws never short. A small building block for 2:1 signal routing and channel selection.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NO | bidirectional | Normally-open analog switch port. Connected to COM when IN is HIGH. Analog signal range 0 V to V+; on-state resistance ~0.75 Ω typ (5 V), peak 1 Ω typ. |
| 2 | GND | power_in | Ground reference for the device supply and control input. |
| 3 | NC | bidirectional | Normally-closed analog switch port. Connected to COM when IN is LOW. Analog signal range 0 V to V+; on-state resistance ~0.75 Ω typ (5 V). |
| 4 | COM | bidirectional | Common analog switch port. Routed to either NO or NC based on the IN control input. Handles ±200 mA continuous on-state switch current, ±400 mA peak. |
| 5 | V+ | power_in | Positive supply voltage, 1.65 V to 5.5 V single-supply operation. Absolute max 6.5 V. Quiescent supply current 0.1 µA max. |
| 6 | IN | input | Digital switch-select input. HIGH connects COM to NO; LOW connects COM to NC. 5-V tolerant regardless of V+; VIH ≥ 2.4 V, VIL ≤ 0.8 V. |
