The TMUX6208 is a precision 8:1, single channel multiplexer while the TMUX6209 is a 4:1, 2 channel multiplexer featuring low on resistance and charge injection. The devices work with a single supply (4.5 V to 36 V), dual supply (±4.5 V to ±18 V), or asymmetric supply (such as VDD = 12 V, VSS = –5 V). The TMUX620x supports bidirectional analog and digital signals onthe source (Sx) and drain (D) pins ranging from V_SS to V_DD.

All logic control inputs support logic high levels from 1.8 V to V_DD, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range. Section 9.3.4 circuitry allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage.

The TMUX620x are part of the precision switches and multiplexers family of devices. These devices have very low on and off leakage currents and low charge injection, allowing them to be used in high precision measurement applications.
