Product Overview
TMUX1113 is a Texas Instruments 4-channel precision SPST switch in the Signal_Chain category. The device structure is four independently selectable 1:1 SPST switches, with source and drain pins supporting bidirectional analog and digital signals. The TMUX1113 control logic is mixed, described as dual open plus dual closed.
The recommended VDD range is 1.08 V to 5.5 V, and the signal path operates from 0 V to VDD for rail-to-rail use. At VDD = 5 V and TA = 25°C, on-resistance is 2 ohm typical and 4 ohm maximum, with 0.85 ohm typical on-resistance flatness and 0.13 ohm typical channel matching. Charge injection is -1.5 pC typical under the stated 5 V test condition.
The device is specified for -40°C to +125°C ambient operation. Package options are PW 16-pin TSSOP and RSV 16-pin UQFN, with junction-to-ambient thermal resistance of 124.7°C/W for TSSOP and 146.8°C/W for QFN. These parameters support compact signal routing, bidirectional switching, and rail-to-rail analog or digital path control.
