This datasheet provides details on the features and applications of the ADG3257 device. The device is a CMOS bus switch comprised of four 2:1 multiplexers/demultiplexers with high impedance outputs. The device is manufactured on a CMOS process, which provides low power dissipation, high switching speed, and very low power consumption.
The ADG3257 is a CMOS bus switch composed of four 2:1 multiplexers/demultiplexers that operate from a single 3.3 V or 5 V supply. It offers bidirectional switching, level‑translation, and isolation functions, making it suitable for bus switching, memory interleaving and mixed‑voltage applications.
Key features include a 0.1 ns typical propagation delay, ultralow quiescent current (1 nA typical), 933 Mbps maximum data rate, and a 16‑lead QSOP package. The device is rated for industrial temperature ranges (‑40 °C to +85 °C) and includes ESD protection.
