Overview
The TMUX7436FPWR is a dual 2:1 analog multiplexer from Texas Instruments featuring ±60 V fault protection and latch-up immunity. It operates on single supplies of 8 V to 44 V or dual supplies of ±5 V to ±22 V. The device includes integrated overvoltage protection up to ±85 V relative to supplies, active-low interrupt flags (FF and SF) for diagnostics, and failsafe logic capable of handling up to 44 V independent of supply voltage. Key electrical parameters include an 8.6 Ω typical on-resistance, 230 MHz bandwidth, and 6 kV HBM ESD rating. It is housed in a 16-pin TSSOP package.
Feature Summary
- Integrated overvoltage protection with active-low interrupt flags for system diagnostics
- Failsafe logic allowing operation with control signals up to 44 V regardless of power state
- Latch-up immunity and high electrostatic discharge tolerance
Applications
- Factory automation and control systems
- Programmable logic controllers (PLC)
- Analog input modules
- Semiconductor test equipment
- Data acquisition systems (DAQ)
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-16 package configuration required for your design. Confirm that the component meets RoHS standards if environmental compliance is mandatory for your manufacturing process. Ensure the selected supplier provides valid traceability documentation for production integration.
Selection Notes
Select this component when high-voltage fault protection is critical for signal integrity. The dual 2:1 configuration supports asymmetric supply voltages, making it suitable for mixed-signal environments. Verify that the maximum continuous current ratings align with your load requirements to prevent thermal issues within the specified operating temperature range.
Part Context
This part belongs to the TMUX7436F series of high-voltage analog switches. It is designed for robust industrial applications requiring reliable signal routing under harsh electrical conditions. The device complements other Texas Instruments multiplexers by offering specific fault detection capabilities not found in standard analog switches.
Replacement Considerations
Check datasheets for alternative parts like the TMUX7436FRPT if a smaller WQFN package is preferred. Ensure any substitute maintains the same ±60 V fault protection level and dual-channel architecture to preserve circuit functionality without redesign.
