SN75HVD08DR

Приемопередатчик RS485, 3В-5.5В, SOIC-8.

The SN75HVD08DR is a RS-485 Wide Supply Range Transceiver for use with point-of-sale network. It combines a 3-state differential line driver and differential line receiver designed for balanced data transmission and interoperation with ANSI TIA/EIA-485-A and ISO-8482E standard-compliant devices. The wide supply voltage range and low quiescent current requirements allow the SN65HVD08s to operate from a 5V power bus in the cable with as much as a 2V line voltage drop. Busing power in the cable can alleviate the need for isolated power to be generated at each connection of a ground-isolated bus. 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. The driver and receiver has active-high and active-low enables respectively, which can be externally connected together to function as a direction control.
