The SN65HVD08 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 5-V power bus in the cable with as

much as a 2-V 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.
