The PD4712C and 4712D are high-voltage silicon gate CMOS line driver/reciever conforming to the EIA/TIA-232-E standard. It can operate with a single +5 V power source because it is provided with a DC-DC converter. In addition, this line driver/receiver has many ancillary functions, including output control, threshold select, and standby functions. Because the PD4712C and 4712D are provided with four output driver circuits and four receiver circuits, it can constitute an RS-232 interface circuit with a single chip. |
