TMUX1121DGKR

Overview

The TMUX1121DGKR is a dual-channel analog switch manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It features two independent SPST (Single-Pole Single-Throw) channels with a maximum on-state resistance of 4 ohms. The device operates within a supply voltage range of 1.08 V to 5.5 V and supports signal voltages up to the supply rail. It is rated for operation between -40°C and +125°C, ensuring reliability in industrial environments.

Feature Summary

Dual-channel configuration providing two independent SPST switches in a compact footprint
Low on-state resistance of 4 ohms maximum for efficient signal transmission
Wide operating temperature range supporting industrial applications

Applications

Signal routing in portable consumer electronics
Multiplexing in data acquisition systems
Battery-powered instrumentation circuits

Selection Notes

Verify that the required channel count matches the dual-SPST architecture. Ensure the system supply voltage falls within the 1.08 V to 5.5 V range. Confirm that the 4-ohm maximum on-resistance meets the signal integrity requirements for the specific application load.

Part Context

This component belongs to the TMUX1121 series of low-voltage analog switches. The DGKR suffix indicates the specific VSSOP-8 packaging and tape-and-reel shipping format. It serves as a compact solution for managing multiple signal paths in space-constrained designs.
