Product Overview
The TMUX1209 is a Texas Instruments Signal_Chain device configured as a dual 4:1 bidirectional multiplexer. Its device comparison data identifies a 4:1, 2-channel differential multiplexer structure, supporting source and drain signal-path voltages from 0 V to VDD across a 1.08 V to 5.5 V recommended supply range.
At VDD = 5 V, the switch path has 5 Ω typical on-resistance, with maximum values specified across both -40°C to +85°C and -40°C to +125°C operating ranges. Matching, flatness, leakage, capacitance, charge injection, off isolation, crosstalk, and 125 MHz typical bandwidth are specified for signal-chain switching analysis.
Control pins EN, A0, A1, and A2 accept 0 V to 5.5 V logic-control input voltage. Logic thresholds, input leakage, logic capacitance, enable timing, transition timing, and break-before-make time are specified for operation over the extended ambient temperature range.
Package options include 16-pin TSSOP (PW) and 16-pin QFN (RSV), with package thermal resistance values provided for junction-to-ambient, junction-to-case top, and junction-to-board calculations.
