Dual differential line driver supports digital data transmission over RS-422 interfaces and can also operate as four independent RS-423 single-ended line drivers. A mode-control input selects between the two-driver differential mode and the four-driver single-ended mode. Differential outputs include individual three-state controls and tolerate a ±10 V common-mode line voltage while in the high-impedance state. The device is intended for party-line and full-duplex systems using compatible AM26LS32 line receivers.
