TPW4053-SR

TPW4053-SR is a triple 2-channel analog multiplexer/demultiplexer (three SPDT switches). Each channel can connect either input Xn or Yn to the common output Zn, controlled by S1, S2, and S3. An INH input disables all three switches.
Key points:
- Three independent SPDT analog switches with a shared control scheme.
- CMOS transmission-gate construction; suitable for routing analog signals.
- Typical power-supply range is broad (check datasheet, commonly a few volts up to 18 V); low on-resistance when on and low-leakage when off.
- Break-before-make behavior helps prevent cross-talk during switching.
- INH disables all channels; signals must stay within supply rails.
Common uses:
- Signal routing and multiplexing in data acquisition, instrumentation, audio, and sensor front-ends.
- Front-end switching for ADCs or signal conditioning networks.
Basic hookup:
- Xn and Yn are the two inputs for channel n; Zn is the output.
- S1, S2, S3 select which input is connected to Zn.
- Ensure all signals stay within VDD/VSS rails.
Packaging: SR typically indicates tape-and-reel for automated assembly. For exact specs and pinout, consult the datasheet.

TPW4053-SR is a TI triple 2-channel analog multiplex/demultiplex (SPDT) switch. Key features:
- 3 independent SPDT switches (Xn to Yn0/Yn1) controlled by S1, S2, S3.
- Wide supply range (typically 3 V to 15–18 V; supports single-supply operation).
- On-resistance: low and relatively stable (typical in the 100–150 Ω range; varies with VDD and temperature).
- Low off leakage and good isolation between channels.
- Analog signals compatible with rail-to-rail range within VSS–VDD.
- Fast switching (tens of nanoseconds typical) with predictable timing.
- Single-ended input/output tolerant within supply rails.
- Available in SR tape-and-reel packaging (SMT leaded package; 14-pin).
- Temp range: industrial (-40°C to +125°C).
Applications: signal routing, data acquisition, switching networks, instrumentation. Note: for exact electrical specs (Ron, leakage, maximum VDD, packing), consult the latest datasheet.

The TPW4053-SR comes in a 16‑pin SOIC (Surface Mount) package.

- Pin count: 14 pins (DIP-14/SO-14 package)
- Function: TPW4053-SR is a triple 2-channel analog multiplexer/demultiplexer (three SPDT analog switches) controlled by S1, S2, and S3. It routes each common port to one of two selectable inputs.
