The ADM3483 / ADM3485 / ADM3488 / ADM3490 / ADM3491 are low power, differential line transceivers designed to operate using a single 3.3 V power supply. Low power consumption, coupled with a shutdown mode, makes the ADM3483/ADM3485/ADM3488/ ADM3490/ADM3491 ideal for power-sensitive applications. The ADM3488 / ADM3490 / ADM3491 feature full-duplex communication, while the ADM3483/ADM3485 are designed for half-duplex communication. The ADM3483 / ADM3488 feature slew rate limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250 kbps. The ADM3485 / ADM3490 / ADM3491 transmit at up to 10 Mbps. The receiver input impedance is 12 kΩ, 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 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. The parts are fully specified over the commercial and industrial temperature ranges. The ADM3483 / ADM3485 / ADM3488 / ADM3490 are available in 8-lead SOIC_N; the ADM3491 is available in a 14-lead SOIC_N.
