Product Overview
The TMUX1119 is a Texas Instruments 2:1 precision analog switch in the Signal_Chain category. Its CMOS SPDT architecture connects either S1 or S2 to D under SEL control, where logic low selects S1 to D and logic high selects S2 to D.
The recommended supply range is 1.08 V to 5.5 V, while the analog signal path supports 0 V to VDD on Sx and D pins. At VDD = 5 V, on-resistance is 1.8 Ω typical and 4 Ω maximum at 25°C, with 0.13 Ω typical channel matching and 0.85 Ω typical flatness across the signal range.
Dynamic specifications include 12 ns typical switching between channels at 5 V, 8 ns typical break-before-make time, -6 pC charge injection, 250 MHz bandwidth, and -65 dB off isolation or crosstalk at 1 MHz. Package options include DCK SC70-6 and DBV SOT-23-6 for compact signal-routing assemblies.
