Overview
The TMUX7213RUMR is a four-channel, 1:1 single-pole single-throw (SPST) analog switch from Texas Instruments. It operates with a single supply voltage range of 4.5 V to 44 V or dual supplies ranging from ±4.5 V to ±22 V. The device features low on-resistance and supports bidirectional signal flow between source and drain pins. It includes integrated pull-down resistors on logic inputs and offers latch-up immunity for robust performance in harsh environments.
Feature Summary
- Supports rail-to-rail bidirectional operation across wide supply ranges
- Provides latch-up immunity to prevent high current events during overvoltage conditions
- Features fail-safe logic control with integrated pull-down resistors
Applications
- EV charging station power modules
- Advanced driver assistance systems (ADAS)
- Automotive gateway and head unit applications
- Analog and digital multiplexing or demultiplexing
- Battery management systems (BMS)
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure that the selected component matches the required logic control configuration and thermal dissipation limits for the intended operating environment before finalizing procurement orders.
Selection Notes
Select this model when both logic high and logic low control signals are required, as indicated by the 'TMUX7213' designation. Compare continuous current ratings and thermal resistance values against system constraints. Verify that the WQFN-16 package meets the board space and heat dissipation requirements for the application design.
Part Context
This component belongs to the TMUX721x family of precision switches manufactured by Texas Instruments. The RUM suffix specifically denotes the 16-pin WQFN package variant. It shares core electrical characteristics with the TMUX7211 and TMUX7212 models but differs in its logic input control requirements.
Replacement Considerations
The TMUX7211RUMR and TMUX7212RUMR are direct pin-compatible alternatives within the same family. Selection depends on whether the system requires logic low only, logic high only, or combined logic control inputs.
