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
