Overview
The TMUX4052PWRQ1 is an automotive-grade, general-purpose CMOS multiplexer featuring a 4:1, 2-channel configuration. It operates with a single supply voltage range of 5 V to 24 V or dual supplies up to ±12 V. The device supports bidirectional analog signals ranging from VSS to VDD and includes rail-to-rail operation. Logic inputs are compatible with 1.8 V thresholds, ensuring compatibility with TTL and CMOS logic families. It provides break-before-make switching to prevent signal overlap during transitions.
Feature Summary
- AEC-Q100 qualified for automotive applications with extended temperature support
- Bidirectional signal path supporting rail-to-rail analog transmission
- 1.8 V logic compatible input thresholds for broad digital interface integration
Applications
- Analog multiplexing and demultiplexing
- Battery management systems (BMS)
- HVAC control modules
- Telematics systems
- On-board charging and wireless charging
Procurement Notes
Verify the specific package variant against the datasheet option addendum, as the TMUX4052-Q1 series is available in TSSOP-16, SOT-23-THIN, and WQFN packages. Confirm that the ordering suffix matches the required thermal and mechanical specifications for the target PCB layout. Ensure the component meets AEC-Q100 Grade 1 requirements for the intended ambient operating temperature range.
Selection Notes
Select this component when designing circuits requiring high-voltage analog signal routing within automotive environments. The wide supply voltage capability allows direct interfacing with battery voltages without external level shifting. Consider the low capacitance specification if signal integrity at higher frequencies is critical for the application bandwidth.
Part Context
This device belongs to the TMUX405x-Q1 family of multiplexers, which also includes the TMUX4051-Q1 (8:1, 1-channel). These devices are designed as pin-compatible replacements for industry-standard 4051 and 4052 muxes while offering improved performance characteristics such as lower on-resistance and higher bandwidth suitable for modern automotive electronics.
Replacement Considerations
The TMUX4052PWRQ1 is functionally equivalent to the non-automotive TMUX4052PWR. For legacy designs, it serves as a drop-in replacement for standard CD4052 or SN74LV4052 devices, provided the supply voltage and logic threshold requirements align with the new specifications.
