Overview
The TMUX4052DYYRQ1 is an automotive-grade analog multiplexer switch IC from Texas Instruments, part of the TMUX405x-Q1 family. It features a 4:1 configuration with two independent channels (Channel A and Channel B). The device supports bidirectional signal paths and operates on a single supply voltage ranging from 5 V to 24 V, or dual supplies up to ±12 V. It utilizes 1.8-V logic compatible inputs for address selection and enable control. Key electrical characteristics include a low off-state capacitance of 3 pF, high ESD protection ratings of 2000 V (HBM), and rail-to-rail operation capabilities.
Feature Summary
- AEC-Q100 qualified for automotive applications with extended temperature range
- Bidirectional signal path supporting rail-to-rail operation
- Low capacitance design minimizing signal distortion
- Break-before-make switching prevents short circuits during transitions
Applications
- Battery management systems (BMS)
- HVAC control modules
- Telematics units
- On-board chargers (OBC) and wireless charging systems
Procurement Notes
Verify the specific ordering suffix DYYRQ1 corresponds to the SOT-23-THIN package and reel packaging format required for your assembly process. Confirm that the component meets the specific AEC-Q100 grade requirements for your target automotive application environment before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring high-voltage analog switching in automotive environments. Ensure the supply voltage differential remains within the 5 V to 24 V range. Verify that the 1.8-V logic thresholds are compatible with the microcontroller or driver interface used for address and enable control signals.
Part Context
This device belongs to the TMUX405x-Q1 series, which includes the TMUX4051-Q1 (8:1, 1-channel) variant. Both devices share pin compatibility with industry-standard 4051 and 4052 multiplexers, facilitating direct upgrades or replacements in existing designs while offering improved performance metrics such as lower capacitance and higher voltage tolerance.
Replacement Considerations
Pin-compatible alternatives within the same family include the TMUX4051-Q1 for single-channel 8:1 applications. Standard industry 4051/4052 CMOS multiplexers may serve as functional substitutes if automotive qualification and high-voltage specifications are not critical constraints.
