The TMUX6119 is a modern complementary metal-oxide semiconductor (CMOS) single-pole, double throw (SPDT) switch. The device works well with dual supplies (±5 V to ±16.5 V), a single supply (10 V to 16.5 V), or asymmetric supplies. Both digital input pins (EN and SEL) have transistor-transistor logic (TTL) compatible thresholds, ensuring both TTL/ CMOS logic compatibility.
The TMUX6119 can be enabled or disabled by controlling the EN pin. When disabled, both channel switches are off. When enabled, the SEL pin can be used to turn on channel A (SA to D) or channel B (SB to D). Each channel conducts equally well in both directions and has an input signal range that extends to the supplies. The switches of TMUX6119 exhibit break-before-make (BBM) switching action.
The TMUX6119 is part of Texas Instruments Precision Switches and Multiplexers family. The TMUX6119 has very low leakage currents and charge injection, allowing the device to be used in high precision measurement applications. The device also provides excellent isolation capability by blocking signal levels up to the supplies when the switches are in the OFF position. A low supply current of 17 µA enables usage in portable applications.
