Beschreibung von TMUX4821
The TMUX48xx is a complementary metal-oxide semiconductor (CMOS) multiplexer with 2 configurations available: 1:1, single-pole, single-throw (SPST) 2-channel (TMUX4821) and 2:1, single-pole, double-throw (SPDT) 1-channel (TMUX4819). This device works with a single supply (1.8V to 5.5V), but can pass bidirectional analog and digital signals beyond the supply from -15V to 15V.
The TMUX48xx also features bidirectional powered off protection up to ±15V, 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 TMUX48xx is an excellent choice for passing precision analog and audio signals without adding distortion.
