Overview
The TMUX1309PWR is a general-purpose CMOS multiplexer featuring two independent 4:1 channels in a 16-pin TSSOP package. It supports bidirectional analog and digital signals ranging from GND to VDD with a supply voltage range of 1.62 V to 5.5 V. Key electrical parameters include a maximum on-resistance (RON) of 195 Ω at 5 V, an off-isolation of -110 dB at 100 kHz, and a bandwidth up to 500 MHz. The device incorporates internal injection current control, fail-safe logic, and break-before-make switching, operating within a temperature range of -40°C to +125°C.
Feature Summary
- Internal injection current control eliminates the need for external protection diodes or resistor networks.
- Bidirectional signal paths support rail-to-rail operation across the full supply voltage range.
- Fail-safe logic allows control voltages to be applied before the power supply without damage.
- Pin-compatible with industry standard 4052 and 4852 multiplexers.
Applications
- Analog and digital multiplexing and demultiplexing
- Diagnostics and monitoring systems
- Data center switches
- Remote radio units (RRU)
- Electricity meters
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-16 package and reel/cut-tape packaging configuration. Confirm that the component meets RoHS compliance requirements for the intended assembly process. Ensure the design accounts for the thermal dissipation characteristics specified for the PW package type during operation.
Selection Notes
Select this component when a dual-channel 4:1 differential multiplexer is required. It is suitable for applications needing low capacitance and high off-isolation. Verify that the system logic levels are compatible with the 1.8 V logic thresholds. Consider the pinout compatibility if replacing legacy 4052 or 4852 designs.
Part Context
This part belongs to the Texas Instruments TMUX13xx family of 5-V bidirectional multiplexers. The TMUX1309 variant specifically provides two 4:1 channels, distinguishing it from the single-channel TMUX1308. Both devices share similar features such as injection current control and wide supply voltage ranges, but differ in channel count and configuration.
Replacement Considerations
The datasheet confirms pin compatibility with industry standard 4052 and 4852 multiplexers. No other specific substitute part numbers are documented in the provided source material.
