TMUX6209PWR

Overview

The TMUX6209PWR is a precision analog multiplexer featuring two independent 4:1 channels in a 16-pin TSSOP package. It operates on single supplies from 4.5 V to 36 V, dual supplies of ±4.5 V to ±18 V, or asymmetric configurations. The device supports bidirectional signal paths ranging from VSS to VDD with rail-to-rail operation. Key electrical characteristics include a maximum on-resistance of 6.2 Ω at 36 V single supply and 5.9 Ω at ±15 V dual supply. It exhibits low charge injection of 3 pC and high current support up to 300 mA in the TSSOP package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the selected component matches the required thermal performance and pin configuration for the target PCB layout design.

Selection Notes

Select this component when designing circuits requiring high-voltage analog switching with low on-resistance. Consider the continuous current ratings relative to the operating temperature and package thermal resistance. Verify that the logic input levels are compatible with the system's control voltage standards.

Part Context

This device belongs to the TMUX620x family of precision multiplexers manufactured by Texas Instruments. The family includes the TMUX6208, which offers an 8:1 single-channel configuration in the same package footprint. Both devices share similar electrical characteristics and are designed for high-precision measurement applications.

FAQ

What is the maximum continuous source or drain current for the TMUX6209PWR?

In the TSSOP package, the maximum continuous current is 300 mA at ±15 V dual supply and 280 mA at +36 V single supply.

How does the TMUX6209 handle logic inputs before power is applied?

It features integrated fail-safe logic circuitry that protects the device from potential damage if voltages are applied to the control pins before the supply pins.

Is the signal path unidirectional or bidirectional?

The TMUX6209 supports a bidirectional signal path on the source and drain pins, allowing signals to flow from VSS to VDD.
