ONSEMI FST3257MTCX bus switch

The FST3257 is a quad 2:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch designed for efficient switching between two data ports. It features minimal propagation delay, low on resistance, and zero bounce in flow-through operation, ensuring high-speed data transfer with low noise. The device's control inputs are TTL-compatible, and when /OE is LOW, the switch connects the A port to the selected B port; when HIGH, it opens, creating a high-impedance state. Suitable for digital communication and high-speed switching applications, this device supports a wide temperature range and healthily passes signals with low distortion, making it ideal for complex electronic systems.
