3 Description

The TMUX2889 is a complementary metal-oxide semiconductor (CMOS) multiplexer with two independently selectable 2:1, single-pole, double-throw (SPDT) switch channels. This device works with a single supply (1.6V to 5.5V), but can pass bidirectional analog and digital signals beyond the supply from -5.5V to 5.5V.

The TMUX2889 also features powered off protection up to ±5.5V, which isolates the switch even when there is no supply voltage present (VDD = 0V). Without this protection feature, any voltage on the switch can back-power the supply rail through an internal ESD diode and cause potential damage to the rest of the system.

With 0.001% THD+N and 1mΩ RON-flatness, the TMUX2889 is designed for passing precision analog and audio signals without adding distortion.
