Overview
The TMUX1309QBQBRQ1 is an automotive-grade, bidirectional analog and digital multiplexer featuring a 4:1 configuration with two independent channels. It operates within a supply voltage range of 1.62 V to 5.5 V and supports rail-to-rail signal paths from GND to VDD. The device incorporates internal injection current control to protect switches and maintain input signals within the supply voltage limits without external components. Key electrical parameters include a maximum on-resistance of 195 Ohms at 5 V, a typical off-isolation of -110 dB, and a bandwidth up to 500 MHz. It utilizes a 16-pin WQFN package and features fail-safe logic for robust operation in demanding environments.
Feature Summary
- AEC-Q100 qualified for automotive applications with extended temperature range
- Internal injection current control eliminates need for external protection networks
- Bidirectional signal path supporting both analog and digital signals
- Fail-safe logic allows control pin voltage application before power supply
Applications
- Automotive body control modules
- Battery management systems (BMS)
- Zonal architecture interfaces
- On-board charging and telematics systems
Procurement Notes
Verify the specific ordering suffix 'BQB' corresponds to the WQFN-16 package variant required for your design. Confirm that the Q1 designation meets your project's AEC-Q100 reliability standards. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability for automotive safety-critical applications.
Selection Notes
Select this component when a dual-channel 4:1 multiplexing solution is required for automotive systems. It serves as a pin-compatible replacement for industry standard 4052 and 4852 multiplexers. Consider its low capacitance and high off-isolation for signal integrity in sensitive diagnostic or monitoring circuits where break-before-make switching is beneficial.
Part Context
This part belongs to the Texas Instruments TMUX13xx-Q1 family of general-purpose CMOS multiplexers. The family includes the TMUX1308-Q1 (8:1 single-ended) and TMUX1309-Q1 (4:1 differential) variants. These devices share common features such as injection current control and wide supply voltage ranges, designed to simplify system design by removing the need for complex external protection circuitry.
Replacement Considerations
Publicly confirmed pin-compatible replacements include the TMUX1309BQBR and TMUX1309QPWRQ1. Verify that non-Q1 variants meet the required operating temperature and reliability specifications if used in automotive contexts.
