The TMUX7309FPWR is a dual 4:1 analog multiplexer from Texas Instruments, housed in a 16-pin TSSOP (PW) package. It operates with a wide supply range of ±5 V to ±22 V dual or 8 V to 44 V single supply. The device features integrated fault protection tolerating ±60 V overvoltage on source pins and ±85 V relative to supplies. It supports 1.8-V logic inputs with fail-safe capabilities up to 44 V independent of the power supply. Key electrical characteristics include an on-resistance of 250 Ω typical at 25°C, low charge injection of -15 pC, and break-before-make switching to prevent signal shorting.
Verify the specific ordering suffix 'G4' against the manufacturer's current product status documentation to confirm active production status and compliance details. Ensure the TSSOP-16 package variant matches the design requirements for thermal management and PCB footprint constraints before finalizing procurement orders.
Select this component when dual-channel 4:1 multiplexing is required with high voltage tolerance. The TMUX7309F is suitable for applications needing robust fault protection without external circuitry. Consider the WQFN package if space is limited, otherwise use the standard TSSOP. Verify that the supply voltage differential remains within the 8 V to 44 V range for optimal performance.
The TMUX7309F belongs to the TMUX730xF family of CMOS analog multiplexers designed for high-voltage applications. It complements the TMUX7308F, which offers an 8:1 single-ended configuration. Both devices share similar fault protection and logic interface features, providing designers with flexible channel configurations for data acquisition and signal routing tasks.
The TMUX7308F is a functional alternative within the same family but provides an 8:1 single-ended configuration instead of the dual 4:1 setup. Designers must verify pin compatibility and channel count requirements when substituting between these two part numbers.
