TMUX8211PWR

Overview

The TMUX8211PWR is a high-voltage analog switch IC featuring four independently controllable single-pole single-throw (SPST) channels. It supports dual supply voltages from ±10 V to ±50 V and single supply voltages up to 100 V, with asymmetric operation capability. The device provides a maximum on-resistance of 5 Ω and maintains an on-resistance flatness of 0.05 Ω. Key electrical specifications include a continuous current rating of 200 mA per channel, input leakage current of 10 pA, and off-isolation of -110 dB. It operates with logic levels as low as 1.8 V and features fail-safe logic inputs capable of handling up to 48 V. The component is housed in a 16-pin TSSOP package.

Feature Summary

• High voltage capability supporting up to 100 V across the supply rails for flexible power configurations.
• Latch-up immunity ensures reliable operation in harsh environments by preventing parasitic high-current events.
• Fail-safe logic circuitry allows control signals up to 48 V independent of the main supply voltage.
• Bidirectional signal paths enable versatile switching for both analog and digital signals.

Applications

• Semiconductor test equipment
• LCD test equipment
• Battery test equipment
• Data acquisition systems (DAQ)
• Programmable logic controllers (PLC)

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-16 package variant required for your design. Confirm that the logic control requirements align with the 1.8-V to 48-V fail-safe input specifications. Ensure thermal management strategies account for the junction-to-ambient resistance values provided in the datasheet for the selected operating temperature range.

Selection Notes

Select this component when designs require high-voltage switching capabilities exceeding standard 30-V or 50-V limits. The TMUX8211PWR is suitable for applications demanding consistent parametric performance across wide supply voltage ranges. Consider the bidirectional nature of the source and drain pins for complex signal routing needs. Evaluate the 1.8-V logic compatibility if interfacing with low-power microcontrollers.

Part Context

The TMUX8211PWR belongs to the Texas Instruments TMUX821x family of high-voltage analog switches. This family includes the TMUX8211, TMUX8212, and TMUX8213, which differ primarily in their logic input activation states. The TMUX8211 specifically activates switches when the logic input is low. All variants share identical electrical characteristics and package options, differing only in control logic polarity.

Replacement Considerations

Direct functional substitutes within the same family include the TMUX8212 and TMUX8213, which offer different logic activation polarities but maintain identical electrical specifications and pinouts.
