Overview
The TMUX4052BQBR is a Texas Instruments CMOS analog multiplexer featuring two independent 4:1 channels in a 16-pin WQFN package. It operates on a single supply from 5V to 24V or dual supplies up to ±12V, supporting bidirectional rail-to-rail signal paths. The device includes logic inputs compatible with 1.8V thresholds and provides ESD protection of 2000V HBM. Key electrical characteristics include a maximum on-resistance of 240Ω at 24V, off-isolation of -95dB at 1MHz, and crosstalk of -90dB. It functions within an ambient temperature range of -55°C to +125°C.
Feature Summary
- Supports bidirectional analog signals across the full supply voltage range
- Features break-before-make switching to prevent signal overlap during transitions
- Includes active-low logic enable for power management control
Applications
- Analog multiplexing and demultiplexing systems
- Factory automation and industrial control circuits
- Battery test equipment and power delivery monitoring
Procurement Notes
Verify the BQBR suffix indicates automotive qualification status by consulting the official datasheet. Confirm the specific WQFN-16 mechanical dimensions and thermal pad requirements against your PCB layout guidelines. Ensure the ordering information matches the exact revision level required for your production run.
Selection Notes
Select this component when a dual-channel 4:1 configuration is required alongside standard 1.8V logic compatibility. It serves as a pin-compatible replacement for industry-standard 4052 devices while offering improved bandwidth and lower capacitance. Evaluate the 240Ω maximum on-resistance against your signal integrity requirements at the target operating voltage.
Part Context
This part belongs to the TMUX405x family of general-purpose CMOS multiplexers. The family includes the TMUX4051 (8:1 single channel) and TMUX4053 (2:1 triple switch). All variants share identical logic interfaces and supply specifications, differing primarily in channel count and internal decoder architecture.
Replacement Considerations
The TMUX4052BQBR is pin-compatible with industry standard 4052 series multiplexers. Verify that legacy replacements meet the 1.8V logic threshold requirements and check if the higher bandwidth and lower capacitance of the TMUX405x series are necessary for the application.
