TMUX121NKGR Description

Short technical summary and product information.

The TMUX121NKGR from Texas Instruments is a bidirectional, 2-channel, 2:1 (SPDT) analog switch designed for high-speed signal routing. It supports protocols including Analog, I2C, I3C, LVDS, and UART, making it versatile for various interface applications.

 

This switch boasts a high bandwidth of 3300 MHz and low on-resistance, typically 3 Ω. It operates with a supply voltage of 3.3V and features 1.8V compatible logic control inputs. The device offers excellent performance characteristics such as low capacitance (1.7 pF typical) and high off-isolation (-56 dB typical).

 

Designed for industrial applications, the TMUX121NKGR operates within an extended temperature range of -40°C to 125°C. It is housed in a compact 10-pin UQFN package measuring 1.4 mm x 1.8 mm, suitable for space-constrained designs. Special features include power-off isolation to prevent current leakage in the powered-down state.
