Overview
The TMUX8108RUMR is a single-channel, 8:1 analog multiplexer manufactured by Texas Instruments in a 16-pin WQFN package. It supports supply voltage differentials from 10 V to 100 V across dual, single, or asymmetric configurations. The device features latch-up immunity and bidirectional signal paths on source and drain pins. Logic inputs support 1.8 V, 3.3 V, and 5 V levels with fail-safe capability up to 48 V independent of the power supply. Electrical characteristics include a maximum on-resistance of 80 Ω at 125°C, off-isolation of -110 dB, and crosstalk of -110 dB. Operating temperature ranges from -40°C to +125°C.
Feature Summary
- High-voltage operation supporting up to 100 V differential supply
- Integrated latch-up immunity for harsh environment reliability
- Fail-safe logic allowing control pin voltage application before power rails
- Bidirectional signal path supporting analog and digital signals
Applications
- Semiconductor test equipment
- Data acquisition systems (DAQ)
- Digital multi-meter (DMM)
- Factory automation and control
- Programmable logic controllers (PLC)
Procurement Notes
Verify the specific RUM package designation against the manufacturer's current orderable addendum to ensure availability status. Confirm that the thermal pad connection aligns with system grounding requirements for optimal performance. Review absolute maximum ratings regarding continuous current limits per channel versus all channels simultaneously to prevent thermal overstress during design validation.
Selection Notes
Select this component when high voltage isolation and consistent parametric performance across wide supply ranges are required. The 8:1 configuration suits applications needing multiple input selection within a single channel. Ensure the control logic voltage compatibility matches the 1.8 V to 5 V input specifications. Consider the WQFN package size constraints and thermal dissipation capabilities relative to the expected ambient operating conditions.
Part Context
This device belongs to the TMUX810x family, which includes the TMUX8109 dual-channel variant. Both share identical electrical characteristics and package options but differ in channel count and configuration. The family is designed for modern high-voltage analog switching applications requiring robust protection features and low distortion metrics.
Replacement Considerations
The TMUX8109 serves as a functional alternative if dual-channel 4:1 multiplexing is preferred over single-channel 8:1 routing. Verify pinout compatibility between TSSOP and WQFN packages if changing form factors. No other direct substitutes are documented in the provided datasheet.
