Frequently Asked Questions
What bandwidth can TMUX1248DCKR support for high-frequency signal routing?
The TMUX1248DCKR provides a 250MHz -3dB bandwidth, enabling accurate switching of wideband analog signals in RF front-ends, video signal paths, and high-speed data acquisition systems operating well above 100MHz without significant signal degradation.
Why is 3157-pinout compatibility important when selecting TMUX1248DCKR?
The 3157-compatible pinout means TMUX1248DCKR can directly replace older SPDT switches in existing 6-pin SOT-23 PCB footprints without any layout changes, saving redesign cost and time while providing improved bandwidth up to 250MHz and lower on-resistance compared to many legacy parts.
Which supply voltage range does the TMUX1248DCKR support?
The device operates from a single 5V supply (maximum 5.5V), making it compatible with standard 5V digital logic rails found in microcontrollers, FPGAs, and signal processors. Its low RON ensures minimal voltage drop and distortion for analog signals in the 0V to 5V range.
How compact is the TMUX1248DCKR package for space-constrained PCB designs?
The SOT-23-6 package measures approximately 2.9mm × 1.6mm, occupying under 5mm² of board area, which makes it one of the smallest form factors available for a 2:1 SPDT analog switch and ideal for wearables, portable instruments, and densely populated mixed-signal PCBs.
