Overview

The ADM3493ARZ 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 it ideal for power-sensitive applications. Designed for half-duplex communication, the ADM3493ARZ features a slew rate limited driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. The receiver input impedance is 96kR, allowing up to 256 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. The receiver contains a failsafe feature that results in a logic high output state, if the inputs are unconnected.
