Overview
The TMUX4051BQBR is a general-purpose CMOS analog multiplexer featuring an 8:1, 1-channel configuration housed in a 16-pin WQFN (BQB) package. It supports single supply voltages from 5V to 24V and dual supplies up to ±12V. The device provides bidirectional signal paths with rail-to-rail operation and 1.8V logic compatibility. Key electrical parameters include a maximum on-resistance of 60 Ohms at 24V, typical off-isolation of -95 dB, and low capacitance of 3pF. Operating temperature ranges from -55°C to +125°C.
Feature Summary
- Pin-compatible with industry standard 4051, 4052, and 4053 muxes
- Break-before-make switching prevents signal overlap during transitions
- Bidirectional signal path supporting analog signals from VSS to VDD
Applications
- Analog multiplexing and demultiplexing
- Factory automation and control systems
- Battery test equipment
- Medical devices
Procurement Notes
Verify the BQB suffix indicates the specific WQFN 16-pin package variant. Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the required automotive or industrial grade specifications if applicable for the target environment.
Selection Notes
Select this component when pin compatibility with legacy 4051 designs is required alongside improved performance metrics. Consider the wide voltage range for applications requiring operation above standard 5V rails. Evaluate thermal resistance values for high-density PCB layouts.
Part Context
This part belongs to the TMUX405x family of multiplexers manufactured by Texas Instruments. The series includes the TMUX4051 (8:1), TMUX4052 (4:1), and TMUX4053 (2:1). The BQB suffix specifically denotes the WQFN package type within this product line.
Replacement Considerations
Direct pin-compatible replacements include other variants within the TMUX405x family such as TMUX4051PW or TMUX4051DYY, provided the package type matches the design constraints.
