0V to 5.
5V powered, single receivers that meet both the RS-485 and RS-422 standards for balanced communication.
These receivers have very low bus currents (+125µA/-100µA), so they present a true “1/8 unit load” to the RS-485 bus.
This allows up to 256 receivers on the network without violating the RS-485 specification’s 32 unit load maximum and without using repeaters.
Receiver inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, s...
