The TS5A3159DCKR is a single-pole double-throw (SPDT) analog switch from Texas Instruments with 1.8V to 5.5V supply range. It features 1\u03a9 on-resistance (Ron), very low Ron flatness (0.25\u03a9), and 200MHz bandwidth, making it ideal for audio, video, and USB signal routing. The DCKR suffix indicates SOT-23-6 package with tape & reel.<\/p>\n

The ultra-low Ron and flatness minimize signal distortion for audio and video routing. Low 5pC charge injection reduces glitch energy in sensitive analog paths. Break-before-make prevents momentary shorting during switching. The tiny SOT-23-6 package and tape & reel packing suit high-volume portable and consumer applications.","working_principle":"The TS5A3159 is a CMOS analog switch using transmission gate topology. The select (SEL) pin controls which of the two NC or NO paths connects to the common (COM) pin. When SEL is low, NC connects to COM; when SEL is high, NO connects to COM. Break-before-make ensures both paths are briefly disconnected during switching to prevent shorting. The 1\u03a9 Ron minimizes voltage drop and signal attenuation. The wide 1.8V to 5.5V supply range supports both 1.8V and 3.3V\/5V signal levels.","pin_description":"
