onsemi Signal Switches, Multiplexers, Decoders FSTU3253MX

The FSTU3253MX is a dual 4:1 multiplexer/demultiplexer bus switch designed for high-speed applications. It features low on-resistance of approximately 4,Ѷ, which minimizes propagation delay and ground bounce noise. The device operates with a supply voltage range of 4.0V to 5.5V and supports input and output voltages from 0V to 5.5V. It includes undershoot protection down to -2.0V, enhancing reliability in environments with potential voltage fluctuations. Control inputs are TTL-compatible, allowing for straightforward integration into existing systems. The switch can be enabled or disabled via the OE inputs, providing flexibility in circuit design. The FSTU3253MX is available in multiple package types, including SOIC, QSOP, and TSSOP, catering to various space and layout requirements. This product is suitable for applications requiring efficient signal routing with minimal delay and noise.
