3.3V Differential Transceiver
The SN65HVD10 SN75HVD10 SN65HVD11 SN75HVD11 SN65HVD12 and SN75HVD12 combine a 3-state differential Line Driver and differential input line receiver that operate with a single 3.3-V power supply. They are designed for balanced transmission lines and meet or exceed ANSI standard TIA/EIA-485-A and ISO 8482:1993. These differential Bus Transceivers are monolithic integrated circuits designed for bidirectional data Communication on multipoint bus-transmission lines. The drivers and receivers have active-high and active-low enables respectively, that CAN be externally connected together to function as direction control. Very low device standby supply current CAN be achieved by disabling the driver and the receiver.
The driver differential outputs and receiver differential inputs connect internally to form a differential input/ output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. These parts feature wide positive and negative common-mode voltage ranges, making them suitable for party-line applications.
