TMUX1121DGKR TI Analog Switch IC | 8-VSSOP | 1.08V-5.5V, 2.4Ω

Product Overview

The TMUX1121DGKR from Texas Instruments is a high-performance single-pole, single-throw (SPST) analog switch designed for precision signal routing in a wide range of applications. Housed in a compact 8-VSSOP package, this device offers low on-resistance (2.4Ω typical) and wide supply voltage range (1.08V to 5.5V), making it ideal for battery-powered and portable equipment. The TMUX1121 features break-before-make switching, low leakage currents, and excellent ESD protection (2kV HBM). It supports bidirectional signal flow and is fully specified for operation from -40°C to +125°C.
