Overview
The TMUX8109RPWR is a high-voltage analog multiplexer switch IC from Texas Instruments, featuring two independent 4:1 multiplexers in a TSSOP-16 package. It supports dual supply voltages ranging from ±10 V to ±50 V and single supply voltages up to 100 V. The device offers a maximum on-resistance of 55 Ohms with a bandwidth of 380 MHz. Key timing parameters include a maximum turn-on time of 3 µs, maximum turn-off time of 650 ns, and propagation delay of 550 ps. It operates within a temperature range of -40°C to +125°C and includes latch suppression for robust performance.
Feature Summary
- Supports high voltage operation with dual supplies up to ±50V or single supply up to 100V
- Features latch suppression to prevent unwanted large current events in harsh environments
- Provides consistent analog parameter performance across the entire power supply voltage range
- Includes fail-safe logic supporting input voltages up to 48V independent of power pins
Applications
- High-voltage bidirectional switching
- Semiconductor test equipment
- LCD test equipment
- Battery test equipment
- Data acquisition systems (DAQ)
Procurement Notes
Verify the specific ordering suffix RPWR against the manufacturer's official datasheet to confirm the TSSOP-16 package and reel packaging configuration. Ensure the component meets RoHS compliance requirements as specified in the technical documentation before procurement.
Selection Notes
Select this component when designing circuits requiring high-voltage signal routing with low distortion. The 4:1 configuration per channel suits applications needing multiple inputs routed to a single output. Verify that the control logic levels are compatible with the integrated pull-down resistors and fail-safe features.
Part Context
This part belongs to the TMUX810x series of high-voltage analog switches. It shares architectural similarities with the TMUX8108 but differs in channel configuration. The series is designed for modern systems requiring flexible power supply options and robust protection features like latch suppression.
Replacement Considerations
Consult the official datasheet for confirmed substitute part numbers within the TMUX810x family. Verify pin compatibility and electrical specifications before replacing the component in existing designs.
