TMUX6213PWR

Overview

The TMUX6213PWR is a precision analog switch featuring four independent 1:1 single-pole, single-throw (SPST) channels in a 16-pin TSSOP package. It supports dual supply voltages from ±4.5V to ±18V and single supply voltages from 4.5V to 36V. The device offers low on-resistance with a maximum of 2.7Ω at 25°C under ±15V dual supply conditions, rising to 4.3Ω at +125°C under 36V single supply. Continuous current support reaches 220mA at 25°C for the TSSOP package. Logic inputs are compatible with 1.8V systems and include integrated pull-down resistors.

Feature Summary

• Supports bidirectional signal transmission across source and drain pins within the full supply voltage range.
• Features fail-safe logic and integrated pull-down resistors on control pins to prevent undefined states.
• Provides rail-to-rail operation allowing signals to span from VSS to VDD without distortion.

Applications

• Sample-and-hold circuits
• Feedback gain switching
• Signal isolation
• Data acquisition systems (DAQ)
• Patient monitoring and diagnostics

Procurement Notes

Verify the specific ordering suffix PWR corresponds to the TSSOP-16 package configuration required for your design. Confirm that the logic control requirements align with the TMUX6213's combined logic high and logic high input specifications. Ensure thermal management strategies account for the specified power dissipation limits in the target operating environment.

Selection Notes

Select the TMUX6213PWR when both logic high and logic low control states are required for channel selection, distinguishing it from the TMUX6211 or TMUX6212 variants. Consider the TSSOP-16 package thermal characteristics if continuous current loads approach the 220mA limit at elevated temperatures. Verify that the 1.8V logic compatibility meets the interface requirements of the controlling microcontroller or FPGA.

Part Context

This component belongs to the TMUX621x family of low-leakage-current precision switches manufactured by Texas Instruments. The family includes complementary models like the TMUX6211 and TMUX6212, which differ primarily in their logic control configurations. The TMUX6213 specifically integrates both logic high and logic high control capabilities within the same device architecture.

FAQ

What is the break-before-make time delay for the TMUX6213?

The break-before-make time delay is typically 27 ns at 25°C under ±15V dual supply conditions and 22 ns under 36V single supply conditions.

How does the on-resistance vary with temperature?

On-resistance increases with temperature; for example, under 36V single supply, it rises from a typical 2.1Ω at 25°C to a maximum of 4.3Ω at +125°C.

Is the TMUX6213 suitable for asymmetric supply applications?

Yes, the device supports asymmetric supplies such as VDD = 12V and VSS = –5V, provided the differential voltage remains within the 4.5V to 36V range.
