TMUX1308QBQBRQ1

Overview

The TMUX1308QBQBRQ1 is an automotive-grade, single-channel CMOS multiplexer with an 8:1 configuration. It operates on a single supply voltage ranging from 1.62 V to 5.5 V and supports bidirectional analog and digital signals across the full rail-to-rail range. The device features internal injection current control and back-powering protection without ESD diode paths to VDD. Packaged in a 16-pin WQFN (BQB) format measuring 3.5 mm by 2.5 mm, it meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Feature Summary

Internal injection current control eliminates external protection components
Back-powering protection prevents unintended power rail energization
Fail-safe logic allows control pin voltage application prior to power supply
Break-before-make switching prevents simultaneous signal path connection

Applications

Automotive body control modules
Battery management systems (BMS)
Zonal architecture signal routing
On-board charging and telematics units

Procurement Notes

Verify the BQB package designation matches the required footprint dimensions of 3.5 mm by 2.5 mm. Confirm that the specific suffix indicates compliance with AEC-Q100 Grade 1 requirements for the intended ambient temperature range. Ensure the ordering part number corresponds exactly to the Texas Instruments manufacturing data sheet specifications.

Selection Notes

Select this component when designing for automotive environments requiring high isolation and robust fault tolerance. The WQFN package provides thermal efficiency suitable for space-constrained PCB layouts. Verify that the system logic levels are compatible with the specified 1.8V thresholds to ensure reliable switching performance under varying supply conditions.

Part Context

This device belongs to the TMUX13xx-Q1 family of general-purpose multiplexers designed specifically for automotive applications. It serves as a direct pin-compatible replacement for industry-standard 4051 and 4851 multiplexers while offering superior electrical characteristics such as lower capacitance and integrated fault protection mechanisms.
