Applications
The TMUX1308QBQBRQ1 is designed for automotive infotainment, ADAS sensor hubs, and body-control modules where multiple analog signals must be routed to a single ADC or signal chain. Its 500 MHz bandwidth and AEC-Q100 qualification make it ideal for video signal selection, RF signal switching, and high-frequency analog routing in vehicle electronics operating over the full −40°C to +125°C automotive temperature range. Industrial test equipment and communications infrastructure can also leverage its wide bandwidth for multiplexing high-speed analog signals.

Frequently Asked Questions
What bandwidth and configuration does TMUX1308QBQBRQ1 support for analog signal switching?
TMUX1308QBQBRQ1 is an 8:1 single-ended analog multiplexer with a nominal bandwidth of 500 MHz. This high bandwidth allows it to route RF, video, and other high-frequency analog signals from 8 input sources to a single output without significant signal degradation, making it suitable for automotive radar, infotainment, and ADAS applications.
Is TMUX1308QBQBRQ1 qualified for automotive use, and what temperature range does it support?
Yes, the TMUX1308QBQBRQ1 carries AEC-Q100 automotive qualification (the Q1 suffix in the part number), confirming reliability in automotive-grade environments. It is rated for operation from −40°C to +125°C, covering the full automotive ambient temperature range required for under-hood and body-control module installations in passenger and commercial vehicles.
How does TMUX1308QBQBRQ1 compare to a standard TMUX1308 in non-automotive industrial designs?
The TMUX1308QBQBRQ1 is the AEC-Q100-qualified automotive variant, while the standard TMUX1308 targets industrial and commercial applications. Both share the same 8:1 mux topology and 500 MHz bandwidth, but the Q1 variant undergoes additional stress testing and quality screening, so it is also acceptable in high-reliability industrial designs that need operation from −40°C to +125°C, though it typically carries a price premium of 10–30% over the standard grade.
What package does TMUX1308QBQBRQ1 use and how does its footprint fit a compact automotive PCB?
TMUX1308QBQBRQ1 is housed in a 16-pin QFN (Quad Flat No-Lead) package, which typically measures 3 mm × 3 mm with a low profile of 0.9 mm. This small, solderable footprint is well suited to densely populated automotive ECU boards where space budgets are tight and vibration resistance is required, as QFN packages have no exposed leads susceptible to mechanical stress.
