Overview
The TMUX1209RSVR is a dual-channel, 4:1 multiplexer switch IC manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.08 V to 5.5 V. The device features a maximum on-resistance of 9 Ohms and supports both analog and digital bidirectional signals. Key switching parameters include a maximum turn-on time and turn-off time of 20 ns each. It is housed in a UQFN-16 package and is designed for surface-mount installation. The component functions within an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports bidirectional analog and digital signal transmission across source and drain pins
- Features fail-safe logic circuits to protect against control pin voltage application prior to power supply
- Provides low power consumption with a maximum supply current of 2.7 uA
Applications
- General-purpose signal routing in portable electronics
- Data acquisition systems requiring multi-channel input selection
- Industrial control applications involving sensor signal multiplexing
Procurement Notes
Verify the specific suffix 'RSVR' corresponds to the UQFN-16 package and reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering part number matches the exact electrical specifications required for the target circuit design.
Selection Notes
Select this component for designs requiring dual 4:1 multiplexing functionality within a compact footprint. The wide supply voltage range accommodates various logic levels, while the low on-resistance ensures minimal signal attenuation. Consider the UQFN-16 package dimensions for PCB layout constraints and thermal management requirements during the initial schematic capture phase.
Part Context
This device belongs to the TMUX1209 series of general-purpose analog switches. It shares functional similarities with other members of the family but is distinguished by its specific channel count and configuration. The RSVR designation identifies the particular package type and tape-and-reel shipping method provided by the manufacturer.
Replacement Considerations
The TMUX1209PWR serves as a pin-compatible alternative utilizing a TSSOP-16 package instead of the UQFN-16 form factor. Designers must evaluate the physical footprint differences and adjust PCB layout accordingly if substituting between these package types.
