Overview
The TMUX7208MPWR is a precision 8:1, single-channel multiplexer from Texas Instruments. It operates with a single supply voltage range of 4.5V to 44V or dual supplies ranging from ±4.5V to ±22V. The device features latch-up immunity and supports bidirectional analog and digital signals on source and drain pins. It includes integrated pull-down resistors on logic pins for fail-safe operation. The component is housed in a 16-pin TSSOP package (PW) measuring 5mm by 6.4mm. It supports an operating temperature range from -55°C to +125°C.
Feature Summary
- Latch-up immune design prevents high current events caused by overvoltage.
- Bidirectional signal path supports both analog and digital signals.
- Integrated pull-down resistors on logic inputs ensure fail-safe logic states.
- Rail-to-rail operation allows full signal swing across the supply range.
Applications
- Avionics flight control units
- Aircraft cockpit displays
- Standalone avionics precision flight control systems
- Interconnect and distribution boxes
- Aerospace and defense equipment
Procurement Notes
Verify the ordering suffix 'PWR' corresponds to the TSSOP-16 package and reel packaging configuration. Confirm that the specific revision level matches the project requirements. Ensure the component meets all environmental specifications for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this part when a single 8:1 multiplexer channel is required with high voltage tolerance up to 44V. The device is suitable for applications demanding low charge injection and precise switching characteristics. Consider the thermal dissipation limits of the TSSOP package if operating at elevated ambient temperatures or high continuous currents.
Part Context
This component belongs to the TMUX72xx family of precision switches and multiplexers. The family is characterized by very low on and off leakage currents, making it appropriate for high-precision measurement applications. The latch-up immunity feature distinguishes these devices for use in harsh industrial and aerospace environments where overvoltage events may occur.
Replacement Considerations
The TMUX7208PWR is a verified substitute within the same product family offering identical electrical performance in the TSSOP-16 package. Verify pin compatibility and package dimensions before substitution.
