Product Overview
The Texas Instruments TMUX4053 is a Signal_Chain 2:1, 3-channel analog switch. Source and drain pins are bidirectional, so the connected pins can operate as inputs or outputs. Analog signal handling spans VSS to VDD, and the device supports rail-to-rail operation across its valid supply configuration.
Supply operation includes a 5 V to 24 V single-supply range and dual supplies up to ±12 V. The device also supports asymmetric supply operation, with an extracted example of VDD = 12 V and VSS = -5 V. Logic inputs use 1.8 V compatible thresholds when operated with a valid supply voltage, and the enable input is active low.
Package options include PW TSSOP-16, DYY SOT-23-THIN-16, and BQB WQFN-16. The VDD and VSS pins each specify 0.1 µF to 10 µF decoupling to GND for operation. The thermal pad is not internally connected and is recommended to be left floating or tied to GND. The device is suited to signal routing, bidirectional analog path selection, and rail-to-rail multiplexing functions within the stated electrical limits.

Procurement Notes
When requesting a quote for TMUX4053, 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 supply configurations does the TMUX4053 support?
The TMUX4053 supports single-supply and dual-supply operation. The extracted datasheet facts specify a 5 V to 24 V single-supply range, dual supplies up to ±12 V, and asymmetric supply support such as VDD = 12 V with VSS = -5 V.
Are the TMUX4053 signal paths bidirectional?
Yes. The source and drain pins can be used as inputs or outputs. Analog signals on the source and drain pins can range from VSS to VDD, and rail-to-rail operation is supported within the valid supply configuration.
What packages are available for the TMUX4053?
The extracted package options for TMUX4053 are PW TSSOP-16, DYY SOT-23-THIN-16, and BQB WQFN-16. The device is also described as pin-compatible with industry-standard 4053 muxes.
How does the TMUX4053 enable input operate?
The enable input is active low. According to the extracted facts, EN high turns all switches off, while EN low enables control through the SELx pins for the switch configurations.
