Overview
The TMUX1209PWR is a dual-channel, 4:1 analog multiplexer switch 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 bidirectional signal paths. Key switching parameters include a maximum turn-on time of 20 ns and a maximum turn-off time of 20 ns. It is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports rail-to-rail operation for both analog and digital signals across the full supply voltage range.
- Features fail-safe logic circuits that protect the device when control pin voltages exceed power supply levels.
- Provides low power consumption with a maximum supply current of 2.7 uA.
Applications
- Analog and digital multiplexing/demultiplexing
- HVAC systems
- Video surveillance equipment
Procurement Notes
Verify the specific suffix PWR confirms the TSSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and ensure the ordering quantity aligns with manufacturer packaging standards. Cross-reference the datasheet revision date to validate parameter accuracy against current production versions.
Selection Notes
Select this component for applications requiring dual 4:1 switching with low on-resistance. Ensure the system voltage remains within the 1.08 V to 5.5 V range. Verify that the 20 ns switching speed meets timing requirements. Consider the TSSOP-16 footprint constraints during PCB layout design.
Part Context
This part belongs to the TMUX1209 series of general-purpose analog switches. It shares functional similarities with the TMUX1208 but offers a different channel configuration. The PWR suffix specifically denotes the plastic small-outline package variant suitable for surface-mount assembly.
Replacement Considerations
The TMUX1209RSVR serves as a direct functional alternative with identical electrical specifications but utilizes a UQFN-16 package instead of TSSOP-16. Verify pinout compatibility and thermal performance differences before substitution.
