The TMUX4827 is a complementary metal-oxide semiconductor (CMOS) multiplexer with 2 selectable 2:1, single-pole, double-throw (SPDT) switch channels. This device works with a single supply ( 1.8 to 5.5 V), but can pass bidirectional analog and digital signals beyond the supply from -12 V to 12 V.
The TMUX4827 also features bidirectional powered off protection up to ±12 V, which isolates the switch even when there is no supply voltage present (V DD = 0 V). 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 1 mΩ R ON-flatness, the TMUX4827 is well suited for passing precision analog and audio signals without adding distortion.
