Overview
The TMUX1204DQAR is a single-channel, 4-to-1 analog multiplexer manufactured by Texas Instruments. It operates with a supply voltage range of 2.7 V to 5.5 V and supports bidirectional signal flow. The device features low on-resistance (Ron) of typically 13 ohms at 5 V and flatness of 10 mV. Key electrical parameters include an off-isolation of -60 dB and a channel-to-channel crosstalk of -80 dB at 1 MHz. The package is a 10-pin WSON with dimensions of 3 mm x 3 mm.
Feature Summary
- Supports bidirectional signal transmission for flexible system design
- Low on-resistance ensures minimal signal attenuation
- High off-isolation reduces leakage between channels
- Compact footprint suitable for space-constrained applications
Applications
- Data acquisition systems requiring signal routing
- Audio signal switching in consumer electronics
- Test and measurement equipment input selection
- Industrial control systems sensor multiplexing
Procurement Notes
Verify the suffix DQAR corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products. Ensure the operating temperature range meets the environmental specifications of the final application environment.
Selection Notes
Select this component when a single-channel 4:1 multiplexer with low Ron is required within a 5-V logic family. Compare against the TMUX1208 if multiple channels or higher channel counts are needed. Verify that the 3x3 mm WSON package fits the PCB layout constraints and thermal requirements of the design.
Part Context
This part belongs to the TMUX120x series of general-purpose analog switches. It shares architectural similarities with other devices in the family but offers a specific 4:1 topology. The DQAR suffix indicates a specific reel quantity and packaging variant distinct from tube or cut-tape options.
Replacement Considerations
Direct pin-compatible alternatives may include the TMUX1204DGSR if different packaging is acceptable. Cross-reference datasheets for Ron variation and power consumption differences before substitution.
