Overview
The TMUX1309BQBR is a general-purpose CMOS multiplexer featuring two independent 4:1 channels in a 16-pin WQFN 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. The device includes internal injection current control, eliminating the need for external protection components. Key electrical parameters include an on-resistance (Ron) maximum of 195 Ohms at 5 V, propagation delay (tPD) of 10 ns at 5 V, and off-isolation of -110 dB at 100 kHz. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Internal injection current control circuitry protects switches and maintains signal integrity without external diodes or resistors.
- Back-powering protection provided by the absence of ESD diode paths to the VDD pin, preventing unintended power rail energization.
- Fail-safe logic allows control voltages to be applied before the supply voltage, protecting the device during power-up sequences.
- Pin-compatible with industry standard 4052 and 4852 multiplexers, facilitating direct upgrades in existing designs.
Applications
- Analog and digital multiplexing and demultiplexing
- Diagnostics and monitoring systems
- Data center switch infrastructure
- Remote radio unit (RRU) applications
- Electricity metering devices
Procurement Notes
Verify the specific BQB suffix indicates the WQFN-16 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design reviews account for the thermal characteristics associated with the exposed pad in this package type.
Selection Notes
Select the TMUX1309BQBR for differential signal routing requiring two independent 4:1 channels. The WQFN package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 1.62 V minimum supply voltage for low-power battery-operated applications requiring rail-to-rail signal handling.
Part Context
This component belongs to the Texas Instruments TMUX130x family of general-purpose CMOS multiplexers. The TMUX1309 variant specifically provides dual 4:1 channel configurations, distinguishing it from the single-channel TMUX1308. Both share identical feature sets including injection current control and fail-safe logic capabilities.
Replacement Considerations
The TMUX1309PW serves as a pin-compatible alternative utilizing the TSSOP-16 package. Designers upgrading from legacy 4052 or 4852 multiplexers can utilize this device for direct replacement without schematic modifications.
