SP485E

SP481E / SP485E Enhanced Low Power Half-Duplex RS-485 Transceivers March 17, 2022 Description The SP481E and SP485E are a family of half-duplex transceivers that meet the specifications of RS-485 and RS-422 serial protocols with enhanced ESD performance. The ESD tolerance has been improved on these devices to over ±15kV for both Human Body Model and IEC61000-4-2 Air Discharge Method. These devices are pin-to-pin compatible with MaxLinear’s SP481 and SP485 devices as well as popular industry standards. As with the original versions, the SP481E and SP485E feature Maxlinear’s BiCMOS design allowing low power operation without sacrificing performance. The SP481E and SP485E meet the requirements of the RS-485 and RS-422 protocols up to 10Mbps under load. The SP481E is equipped with a low power shutdown mode. FEATURES ■ 5V only ■ Low power BiCMOS ■ Driver / receiver enable for multi-drop configurations ■ Low power shutdown mode (SP481E) ■ Enhanced ESD specifications: ■ ±15kV Human Body Model ■ ±15kV IEC61000-4-2 Air Discharge ■ ±8kV IEC61000-4-2 Contact Discharge ■ Available in RoHS compliant, lead free packaging.
