Product Overview
TMUX4051 is a Texas Instruments 8:1 analog multiplexer in the Signal_Chain category. The device provides one channel with an 8:1 multiplexer configuration, using A2, A1, and A0 address inputs to select one of the S0-S7 source pins when the active-low EN input is enabled.
The signal path is bidirectional, so source and drain pins can be used as either inputs or outputs. Analog signals are supported across the VSS to VDD range, with rail-to-rail operation. Supply operation includes a 5 V to 24 V single-supply range, dual supplies up to ±12 V, and asymmetric operation such as VDD = 12 V with VSS = -5 V.
Available packages are PW TSSOP-16, DYY SOT-23-THIN-16, and BQB WQFN-16. The common drain D is on pin 3, VDD is on pin 16, VSS is on pin 7, and GND is on pin 8. Recommended decoupling is 0.1 µF to 10 µF from VDD to GND and from VSS to GND.

Procurement Notes
When requesting a quote for TMUX4051, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What multiplexer configuration does the TMUX4051 provide?
The TMUX4051 provides an 8:1, 1-channel analog multiplexer configuration. Selection is controlled through A2, A1, and A0 address inputs when the active-low EN pin enables address-controlled switch selection.
What supply ranges are supported by the TMUX4051?
The TMUX4051 supports single-supply operation from 5 V to 24 V and dual-supply operation up to ±12 V. The extracted datasheet facts also note an asymmetric supply example using VDD = 12 V and VSS = -5 V.
Which packages are listed for the TMUX4051?
The listed TMUX4051 package options are PW TSSOP-16, DYY SOT-23-THIN-16, and BQB WQFN-16. The package_case field combines these three manufacturer package options.
How should the TMUX4051 supply pins be decoupled?
For the listed supply pins, the extracted facts recommend a 0.1 µF to 10 µF capacitor between VDD and GND and a 0.1 µF to 10 µF capacitor between VSS and GND for operation.
