The ADG3249 is a 2.5 V or 3.3 V, high performance 2:1 multiplexer/demultiplexer bus switch. It is designed on a low voltage CMOS process, which provides low power dissipation yet gives high switching speed and very low on resistance. This allows the input to be connected to any 1.8 V, 2.5 V or 3.3 V power supply, and provides optimum system performance. The ADG3249 features 4.5 µΩ switch connection resistance and 225 ps switching delay, enabling high bandwidth, low power and low noise applications.
The ADG3249 is a high‑performance 2:1 multiplexer/demultiplexer bus switch designed for low‑voltage CMOS processes. It provides low power dissipation, fast switching speed, and very low on‑resistance, making it suitable for level‑translation applications such as 3.3 V to 1.8 V or 2.5 V to 1.8 V voltage translation, docking stations, and memory switching.
Key specifications include a 225 ps propagation delay, 1.244 Gbps maximum data rate, 610 MHz small‑signal bandwidth, and operation from either a 2.5 V or 3.3 V supply. The device is supplied in a compact 8‑lead SOT‑23 package.
