The ADG3245 is a 2.5 V/3.3 V, 8-bit, 2-port digital switch. It is designed on Analog Devices’ low voltage CMOS process, which provides low power dissipation yet gives high switching speed and very low on resistance, allowing inputs to be connected to outputs.
The ADG3245 is a 2‑port digital switch that operates from a 2.5 V or 3.3 V supply. It provides fast level translation and bus switching with extremely low on‑resistance and propagation delay, making it suitable for high‑speed data interfaces and DSP/microcontroller interconnects.
Key features include 225 ps propagation delay, 1.244 Gbps maximum data rate, 610 MHz small‑signal bandwidth, and availability in 20‑lead TSSOP and LFCSP packages. The device supports bidirectional signal routing, bus enable control, and selectable level‑shifting via the SEL pin.
