Product Overview
The TMUX1134 is a Texas Instruments Signal_Chain device configured as a 4-channel 2:1 SPDT precision switch. The source and drain signal path is bidirectional, supports rail-to-rail operation from VSS to VDD, and is controlled through EN and SELx logic inputs with a recommended logic-control range of 0 to 5.5 V.
The device operates from a 1.08 to 5.5 V single supply or from dual supplies to ±2.75 V. Electrical characteristics include 2 Ω on-resistance, 3 pA low leakage current, -1 pC charge injection, and 8 nA supply current. Logic thresholds are compatible with 1.8 V logic across the valid supply range, and the switch uses break-before-make behavior.
TMUX1134 is supplied in the PW package, a 20-pin TSSOP. Recommended assembly guidance includes 0.1 µF to 10 µF decoupling capacitors from VDD to GND and from VSS to GND, connecting VSS to GND for single-supply applications, and either grounding or floating the N.C. pin 15.

Procurement Notes
When requesting a quote for TMUX1134, 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.
