The FSAL200MTCX from onsemi is a high-performance, 4-channel SPDT (Single Pole Double Throw) analog switch designed for precision signal routing in low-voltage applications. Packaged in a compact 16-TSSOP and available in Tape & Reel (TR), this IC is optimized for 3V to 5.5V operation, making it suitable for battery-powered and portable electronics. With an on-state resistance (Ron) of just 12Ω (max) and low channel-to-channel matching (ΔRon) of 400mΩ, it ensures minimal signal distortion and high accuracy. Despite being obsolete, it remains a reliable choice for legacy designs due to its robust performance and ROHS3/REACH compliance.
The FSAL200MTCX excels in low-voltage, high-speed signal switching with its low Ron, fast response, and excellent channel matching. While marked obsolete, its 137MHz bandwidth, low charge injection, and 4-channel SPDT architecture make it a standout for precision applications. Engineers working on portable, industrial, or legacy systems will find its balance of performance and reliability invaluable. For designs demanding low distortion and high integration, this IC remains a technically compelling option.
