Each device includes a differential driver and differential receiver. All devices operate from a 3.3V supply. High receiver input impedance allows a large number of transceivers to share a common data bus without the amplitude of excessive maintenance and loading or using expensive repeater signals. The high-impedance driver output is maintained over the entire common-mode voltage range from -7 to +12 V when the receiver fails safe to output as logic 1, input open, short, or terminate. The driver includes built-in short-circuit protection and thermal overload shutdown to prevent excessive power consumption from bus contention or cable failure. All receiver inputs and RS485 driver outputs are ESD protected up to ± 15kV (air-gapped and mannequin) and up to ± 8kV contact discharge (IEC 1000-4-2).
