TMUX1309QDYYRQ1

Overview

The TMUX1309QDYYRQ1 is an automotive-grade, bidirectional 4:1 dual-channel multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 1.62V to 5.5V and supports rail-to-rail analog and digital signals. The device features internal injection current control and back-powering protection without ESD diode paths to VDD. Key electrical parameters include a maximum on-resistance (Ron) of 270Ω at 5V, typical off-isolation of -110dB at 100kHz, and a bandwidth up to 500MHz. It utilizes a 16-pin SOT-23-THIN package and complies with AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Feature Summary

Internal injection current control eliminates the need for external protection networks.
Back-powering protection provided by the absence of internal diode paths to the supply pin.
Fail-safe logic allows control voltages to be applied prior to power-up.
Break-before-make switching prevents simultaneous connection of multiple inputs.

Applications

Analog and digital multiplexing and demultiplexing
Automotive body control modules and HVAC control systems
Battery management systems (BMS)
Zonal architecture and telematics units

Procurement Notes

Verify the specific ordering suffix 'DYYR' corresponds to the SOT-23-THIN 16-pin package and tape-and-reel quantity. Confirm that the 'Q1' designation meets the required AEC-Q100 reliability standards for the target automotive application environment.

Selection Notes

Select this component when a dual-channel differential multiplexer is required for automotive environments. Ensure the design accommodates the 1.62V minimum supply voltage and verify that the 270Ω maximum on-resistance at 5V satisfies the signal integrity requirements of the connected circuitry.

Part Context

This part belongs to the TMUX13xx-Q1 family of general-purpose CMOS multiplexers. It serves as the dual-channel counterpart to the single-channel TMUX1308-Q1. Both devices share identical pinouts and feature sets, allowing for flexible system design based on channel count requirements.

Replacement Considerations

The TMUX1309QPWRQ1 offers the same functional specifications in a TSSOP-16 package. Designers requiring a different footprint may substitute this part while maintaining electrical compatibility.

FAQ

How does the device handle input signals exceeding the supply voltage?

The internal injection current control circuitry allows signals on disabled paths to exceed the supply voltage without affecting the enabled path or damaging the device.
