SN65HVD05D

The SN65HVD05D is a RS-485 High-output Transceiver designed for balanced data transmission and interoperates with ANSI TIA/EIA-485-A and ISO 8482E standard-compliant device. The SN65HVD05 combines a 3-state differential line driver and differential line receiver. The driver is designed to provide a differential output voltage greater than that required by this standard for increased noise margin. The driver and receiver has 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. This device features wide positive and negative common-mode voltage ranges, making them suitable for party-line applications.

• Open-circuit, idle-bus and shorted-bus failsafe receiver
