ADG3257 is a CMOS bus switch comprised of four 2:1 multiplexers/demultiplexers with high impedance outputs. The device is manufactured on a CMOS process. This provides low power dissipation yet high switching speed and very low parasitic capacitance.
The ADG3257 is a CMOS bus switch comprised of four 2:1 multiplexers/demultiplexers with high‑impedance outputs. It operates from a single 3.3 V or 5 V supply and provides bidirectional switching, level translation, and bus isolation.
Key features include a typical propagation delay of 0.10 ns, 2 Ω on‑resistance, ultralow quiescent current (~1 µA), and a maximum data rate of 933 Mbps. The device is offered in a 16‑lead QSOP package and is rated for industrial temperature ranges from –40 °C to +85 °C, making it suitable for bus switching, memory interleaving, and mixed‑voltage applications.
