Product Overview
The TMUX4052 is a Texas Instruments Signal_Chain device configured as a 4:1, 2-channel CMOS multiplexer. Its source and drain pins are bidirectional, allowing either side of the signal path to be used as input or output, with analog signal levels spanning from VSS to VDD.
Supply options include a 5 V to 24 V single supply, dual supplies up to ±12 V, or asymmetric operation such as VDD = 12 V and VSS = -5 V. Control is handled through A1 and A0 address inputs with an active-low EN pin; EN high turns all switches off, while EN low enables the address-selected switch.
The device is available in PW (TSSOP, 16), DYY (SOT-23-THIN, 16), and BQB (WQFN, 16) package options. Recommended assembly guidance includes 0.1 µF to 10 µF decoupling from VDD to GND and VSS to GND. The thermal pad is not internally connected and is recommended to be left floating or tied to GND.

Procurement Notes
When requesting a quote for TMUX4052, 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 type of device is the TMUX4052?
The TMUX4052 is a Texas Instruments 4:1, 2-channel CMOS multiplexer in the Signal_Chain category. It provides bidirectional source and drain signal paths and supports analog signals over the VSS to VDD range.
What supply configurations does the TMUX4052 support?
The TMUX4052 supports single-supply operation from 5 V to 24 V, dual-supply operation up to ±12 V, and asymmetric supplies. One extracted example is VDD = 12 V with VSS = -5 V.
How are TMUX4052 channels selected?
Channel selection uses A1 and A0 address inputs when EN is low. The enable input is active low: EN high turns all switches off, and EN low enables the switch selected by the address inputs.
What package options are listed for TMUX4052?
The listed package options are PW (TSSOP, 16), DYY (SOT-23-THIN, 16), and BQB (WQFN, 16). The thermal pad is not connected internally and is recommended to be left floating or tied to GND.
