Overview
The TMUX1237DCKR is a single-channel, general-purpose analog switch manufactured by Texas Instruments. It features a Single Pole Double Throw (SPDT) configuration housed in an SC-70 package. The device operates on a single supply voltage ranging from 1.08 V to 5.5 V. Key electrical specifications include a maximum on-resistance of 5 Ohms and a maximum supply current of 2.6 uA. It supports a wide operating temperature range from -40°C to +125°C.
Feature Summary
- Provides SPDT switching capability for signal routing applications
- Operates with low supply current consumption suitable for power-sensitive designs
- Compatible with standard logic control voltages for direct interface
Applications
- General-purpose signal switching in portable electronics
- Battery-powered measurement equipment
- Data acquisition systems requiring low power consumption
Procurement Notes
Verify the specific suffix DCKR against the manufacturer's official datasheet to confirm the SC-70 package type and tape-and-reel packaging details. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with the distributor's catalog to confirm availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a single SPDT switch is required within a compact SC-70 footprint. It is appropriate for applications needing operation down to 1.08 V. Compare the 5 Ohm on-resistance against circuit requirements. Consider the 2.6 uA supply current for battery life calculations. Verify thermal performance at the upper limit of the specified operating temperature range.
Part Context
This component belongs to the TMUX12xx series of analog switches from Texas Instruments. These devices are designed for low-power, space-constrained applications. The series typically offers high bandwidth and low charge injection. This specific model represents a single-channel variant optimized for general-purpose use cases where minimal board area is critical.
