ADM3490ARZ

产品概述

The ADM3490ARZ is a low power Differential Line Transceiver designed to operate using a single 3.3V power supply. Low power consumption, coupled with a shutdown mode, makes the ADM3490 ideal for power-sensitive applications. The receiver input impedance is 12kR, allowing up to 32 transceivers to be connected on the bus. A thermal shutdown circuit prevents excessive power dissipation caused by bus contention or by output shorting. If a significant temperature increase is detected in the internal driver circuitry during fault conditions, then thermal shutdown circuit forces the driver output into a high impedance state. If the inputs are unconnected (floating), the receiver contains a fail-safe feature that results in a logic high output state. The part is fully specified over the commercial and industrial temperature ranges.
