Overview
The TMUX8212RUMR is a high-voltage analog switch IC featuring four independently controllable 1:1 single-pole single-throw (SPST) channels. It supports dual supply voltages from ±10 V to ±50 V, asymmetric configurations, and single supplies up to 100 V. The device provides bidirectional signal paths with a maximum continuous current of 200 mA per channel. Key electrical parameters include an on-resistance (RON) of 5 Ω typical, low off-leakage current of 10 pA typical, and crosstalk of -110 dB. 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.
Feature Summary
- High voltage operation supporting up to 100 V single supply or ±50 V dual supply
- Latch-up immunity for reliable performance in harsh environments
- Fail-safe logic allowing control signals up to 48 V independent of supply rails
- Bidirectional signal path with low on-resistance flatness of 0.05 Ω
Applications
- High voltage bidirectional switching
- Semiconductor test equipment
- LCD test equipment
- Battery test equipment
- Data acquisition systems (DAQ)
Procurement Notes
Verify the specific ordering suffix RUMR corresponds to the WQFN-16 package with reel packaging before procurement. Confirm that the logic input configuration matches the TMUX8212 variant, which activates switches on logic high. Ensure supply voltage requirements align with the 10 V to 100 V operational range specified in the datasheet.
Selection Notes
Select the TMUX8212RUMR when high voltage isolation and latch-up immunity are required. The TMUX8212 variant specifically enables channels on a logic high input, distinguishing it from the TMUX8211 (logic low enable). Consider the WQFN-16 package thermal characteristics if operating at high ambient temperatures or utilizing multiple channels simultaneously.
Part Context
The TMUX8212RUMR belongs to the TMUX821x family of modern high-voltage analog switches. This family includes the TMUX8211, TMUX8212, and TMUX8213, which differ primarily in their logic activation states. All variants share identical electrical specifications regarding voltage handling, current capacity, and signal integrity.
Replacement Considerations
Public confirmed substitutes include TMUX8211RUMR and TMUX8213RUMR. Note that these alternatives have different logic activation polarities compared to the TMUX8212.
