Overview
The TMUX4052BQBRQ1 is an automotive-grade, 4:1, 2-channel CMOS multiplexer from Texas Instruments. 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 and digital signals ranging from VSS to VDD on its source and drain pins. Key electrical characteristics include a typical on-resistance of 60 Ω at 25°C, low capacitance of 3 pF, and high off-isolation of -95 dB. It features 1.8 V logic compatible thresholds for address inputs and includes break-before-make switching functionality.
Feature Summary
- AEC-Q100 qualified for automotive applications with extended temperature grades
- Bidirectional signal path supporting rail-to-rail operation
- Low capacitance design ensuring minimal signal distortion
- Break-before-make switching prevents input shorting during transitions
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 ordering suffix BQB corresponds to the WQFN-16 package configuration required for your PCB layout. Confirm that the component meets AEC-Q100 Grade 1 requirements for your target ambient operating temperature range. Ensure supply voltage differentials remain within the specified 5 V to 24 V limits during operation.
Selection Notes
Select this component when designing circuits requiring dual-channel multiplexing in automotive environments. It serves as a pin-compatible replacement for industry standard 4052 muxes while offering superior performance metrics such as lower capacitance and higher bandwidth. Consider the WQFN package for space-constrained designs requiring efficient thermal dissipation.
Part Context
This part belongs to the TMUX405x-Q1 family of general-purpose CMOS multiplexers manufactured by Texas Instruments. The family includes the TMUX4051-Q1 (8:1, 1-channel) and TMUX4052-Q1 (4:1, 2-channel). These devices are designed to replace legacy analog switches with modern automotive-grade specifications, providing enhanced reliability and signal integrity for critical vehicle systems.
Replacement Considerations
The TMUX4052BQBRQ1 is pin-compatible with industry standard 4052 multiplexers. Designers replacing legacy parts should verify that the new device's 1.8 V logic thresholds are compatible with existing control circuitry. Ensure that the power supply rails support the minimum 5 V differential required for proper operation.
