Overview
The TMUX6202RQXR is a single-channel, 1:1 (SPST) precision analog switch manufactured by Texas Instruments. It operates with a single supply voltage ranging from 4.5 V to 36 V or dual supplies from ±4.5 V to ±18 V. The device features a low on-resistance of 1.2 Ω and supports bidirectional signal paths from VSS to VDD. It includes integrated pull-down resistors on logic pins, fail-safe logic for power sequencing protection, and 1.8V logic compatibility. The component is housed in an 8-pin WQFN package.
Feature Summary
- Fail-safe logic circuitry allows control pin voltages to be applied before the power supply without causing damage.
- Bidirectional signal path supports both analog and digital signals across the full supply range.
- Integrated pull-down resistors on logic inputs ensure defined states when unconnected.
Applications
- Optical networking
- Wired networking
- Factory automation and industrial controls
- Semiconductor test equipment
- Data acquisition systems
Procurement Notes
Verify the specific ordering suffix RQX corresponds to the WQFN-8 package configuration required for your design. Confirm that the active-high logic selection matches your system control requirements. Ensure the selected component meets all absolute maximum ratings regarding supply voltage differentials and continuous current limits for your intended operating conditions.
Selection Notes
Select the TMUX6202RQXR when a single-pole single-throw configuration with active-high enable logic is required. This part is suitable for applications needing rail-to-rail operation and low charge injection. Consider thermal dissipation limits if operating at high ambient temperatures or maximum continuous currents within the WQFN package constraints.
Part Context
This component belongs to the TMUX620x family of CMOS switches designed for precision switching applications. The TMUX6202 variant specifically utilizes active-high logic on the SEL pin, distinguishing it from the TMUX6201 which uses active-low logic. Both share identical electrical characteristics and package options, allowing for flexible design integration based on control logic polarity.
Replacement Considerations
TMUX6201RQXR serves as a direct functional substitute if the application requires active-low logic control instead of active-high. Other members of the TMUX620x family may offer different channel counts or package types but maintain similar electrical performance profiles.
