Details
The FST3253MX is designed to meet the demands of high-speed applications that require low distortion and high bandwidth. With three differential 2:1 multiplexers/demultiplexers, single-ended or differential inputs, and complementary outputs, this device operates from a single 3.3V to 5.5V supply. Its low ON resistance (5Ω typical) and high OFF isolation (60dB at 10MHz) make it suitable for a range of applications, including video and data switching, communication systems, and instrumentation. Featuring a propagation delay of less than 7ns, it enables fast switching in time-critical situations. Housed in a space-saving 20-pin TSSOP package, the FST3253MX is well-suited for designs with limited board space. Its low power consumption and high-speed operation also make it an excellent choice for battery-powered portable devices and high-speed data transmission systems
Key Features
- 4Ω switch connection between two ports.
- Minimal propagation delay through the switch.
- Low lCC.
- Zero bounce in flow-through mode.
- Control inputs compatible with TTL level.
