Product Introduction
TMUX1309QDYYRQ1 is a dual-channel SPDT (Single-Pole-Double-Throw) analog switch, also known as a 2:1 multiplexer. It contains two independent SPDT switches, each controlled by a logic input pin. Operating from 1.65V to 5.5V with 3.5Ω typical ON-resistance and 300MHz bandwidth, it is ideal for signal routing in automotive, industrial, and portable electronics. The tiny SOT-23-6 package is AEC-Q100 Grade 1 qualified.
Expert Technical Insights
SPDT switch signal routing applications:
- The TMUX1309's dual SPDT configuration is perfect for audio source selection (routing one audio output between two speakers or headphones), voltage rail switching in power management, and USB-C alternate mode signal routing
- When IN is high, COM connects to NO; when IN is low, COM connects to NC
- The break-before-make timing prevents momentary short circuits during switching.
Why low RON matters in precision analog circuits:
- 3.5Ω ON-resistance causes a voltage divider effect in the signal path, reducing signal amplitude at high load impedance
- For audio signals (typical 10kΩ input impedance), the 3.5Ω loss is negligible (~0.035%)
- For high-impedance sensor inputs (>1MΩ), the impact is even smaller
- The 5pF ON-capacitance limits bandwidth to 300MHz but is low enough for USB 2.0 (480Mbps) and audio applications.
Key Benefits
Two independent switches in a tiny 2.9x1.6mm package, ideal for space-constrained designs.
Compatible with 1.8V, 2.5V, 3.3V, and 5V systems without level shifting.
Suitable for USB 2.0, audio, and general-purpose analog signal switching.
Automotive-qualified with -40°C to +125°C junction temperature range.
