MS1585/MS1585M/MS1585D
Non-polar RS-485 interface circuit
PRODUCT DESCRIPTION
The MS1585/MS1585M/MS1585D is a RS-485 transceiver with with
automatic bus-polarity correction.The bus pins are robust to electrostatic
discharge (ESD) events, with high levels of protection to Human-Body
Model (HBM, ±20kV), Air-Gap Discharge, and Contact Discharge
specifications, the Data Rate can transmit up to 10Mbps. The driver
differential outputs and the receiver differential inputs are connected
internally to form a bus port suitable for half-duplex communication.
FEATURES
Bus-Pin Protection:
±20 kV HBM protection
±12 kV IEC61000-4-2 Contact Discharge
+4 kV IEC61000-4-4 Fast Transient Burst
Up to 256 Nodes on a Bus
Bus-Polarity Correction Within 76 ms
Data Rate: 300 bps to 10Mbps
Power range:4.5V-6.0V
