Overview
The TMUX4053BQBR is a general-purpose CMOS multiplexer switch IC from Texas Instruments, configured as a 2:1, 3-channel switch. It operates with a single supply voltage range of 5V to 24V or dual supplies up to ±12V. The device supports bidirectional analog and digital signals on source and drain pins ranging from VSS to VDD. Key electrical parameters include a maximum on-resistance of 60Ω at 24V, typical off-isolation of -95dB, and low capacitance of 3pF. It features 1.8V logic compatible thresholds for TTL and CMOS compatibility, break-before-make switching, and an operating temperature range of –55°C to +125°C.
Feature Summary
- Supports bidirectional signal paths for both analog and digital applications across the full supply voltage range.
- Features 1.8V logic compatible input thresholds ensuring seamless integration with standard TTL and CMOS logic families.
- Incorporates break-before-make switching mechanism to prevent short circuits during channel transitions.
Applications
- Analog multiplexing and demultiplexing
- Factory automation and control systems
- Battery test equipment
Procurement Notes
Verify the specific ordering suffix BQBR corresponds to the WQFN-16 package configuration when sourcing. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure proper ESD handling procedures are followed during storage and installation due to the CMOS technology used in the device construction.
Selection Notes
Select this component when a compact 3-channel 2:1 switching solution is required within a 16-pin form factor. The wide supply voltage capability makes it suitable for industrial environments requiring robust power rail flexibility. Consider the thermal characteristics of the WQFN package if high ambient temperatures or significant power dissipation are expected in the final application design.
Part Context
This device belongs to the TMUX405x family of general-purpose CMOS multiplexers, which also includes the TMUX4051 (8:1, 1-channel) and TMUX4052 (4:1, 2-channel). The family shares common electrical characteristics and pinout compatibility with industry-standard 4053 muxes, facilitating direct upgrades in existing designs without major schematic modifications.
Replacement Considerations
The TMUX4053BQBR is pin-compatible with industry standard 4053 multiplexers. Verify functional equivalence regarding on-resistance and leakage specifications before substituting legacy components.
