 However one driver can fan-out to up to ten receivers.RS-422 can interoperate with interfaces designed to MIL-STD-188-114B, but they are not identical.RS-422 uses a nominal 0 to 5 volt signal while MIL-STD-188-114B uses a signal symmetric about 0 V. However the tolerance for common mode voltage in both specifications allows them to interoperate.
