Product Overview
The TMUX1112 is a Texas Instruments Signal_Chain device described as a 4-channel SPST precision switch. Its switch configuration is 4-channel 1:1 SPST, and the TMUX1112 control logic is active high and normally open, making each channel controlled by its corresponding SELx input.
The device operates with a recommended VDD range of 1.08 to 5.5 V. Source and drain signal pins support 0 to VDD signal path voltages, while SELx logic control inputs support 0 to 5.5 V. At VDD = 5 V, the on-resistance is 2 Ω typical and 4 Ω maximum at 25 °C, with maximum limits specified across -40 °C to +85 °C and -40 °C to +125 °C.
TMUX1112 is available in PW TSSOP 16-pin and RSV UQFN 16-pin packages. Electrical data includes low off and on leakage current, 1 pF typical logic input capacitance, 0.008 µA typical supply current, 12 ns typical transition time, and -1.5 pC typical charge injection. The specified operating ambient temperature range is -40 to +125 °C.
