High-Output RS-485 Transceiver

The SN65HVD05 SN75HVD05 SN65HVD06 SN75HVD06 SN65HVD07 and SN75HVD07 combine a 3-state differential Line Driver and differential line receiver. They are designed for balanced data transmission and interoperate with ANSI TIA/EIA-485-A and ISO 8482E standard-compliant devices. The driver is designed to provide a differential output voltage greater than that required by these standards for increased noise margin. The drivers and receivers have active-high and active-low enables respectively, which CAN be externally connected together to function as direction control.
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 not powered. These devices feature wide positive and negative common-mode voltage ranges, making them suitable for party-line applications.
