ADM3491ARZ-REEL7

ADM3491 is a low power, differential line transceiver. Low power consumption, coupled with a shutdown mode, makes the device ideal for power-sensitive applications. 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 the 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. It is widely used in application such as low power RS-485/RS-422 applications, telecom, industrial process control, HVAC.
