TMUX6219 2:1 (SPDT) One-Channel Multiplexer
Texas Instruments' SPDT CMOS switch has 1.8 V logic control and works with a single supply, dual supplies, or asymmetrical supplies
Texas Instruments' TMUX6219 is a complementary metal-oxide semiconductor (CMOS) switch in a single-channel SPDT configuration. The device can use a single supply (4.5 V to 36 V), dual supplies (±4.5 V to ±18 V), or asymmetric supplies (VDD: 5 V, VSS: -8 V). The switch supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from VSS to VDD.
The TMUX6219 is enabled or disabled by controlling the EN pin. When disabled, the signal path switches are off. When enabled, the SEL pin can turn on signal path 1 (S1 to D) or signal path 2 (S2 to D). The logic control inputs support a logic level range of 1.8 V to VDD, ensuring TTL and CMOS logic compatibility when operating in the valid supply voltage range. The fail-safe logic circuitry allows the application of control pin voltages before the supply pin, protecting the device from potential damage.
The TMUX6219 is part of the precision switches and multiplexers family of devices. These devices have very low on/off leakage currents and low charge injection, making the device suitable for high-precision measurement applications.
