UPD4721 Datasheet Rs-232 Line Driver/receiver At 3.3 V/5 V

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µP D 4 7 2 1 RS-232 LINE DRIVER/RECEIVER AT 3.3 V/5 V The µPD4721 is a high-breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232E standard. The internal DC/DC converter can switch between multiple voltages, realizing the allowing it to operate with a single +3.3 V or +5 V power supply. It also provides standby function. This IC incorporates 2 driver circuits and 2 receiver circuits. An RS-232 interface circuit can be easily configured by connecting 5 capacitors externally.

Key Features

  • Conforms to EIA/TIA-232-E (former name, RS-232C) standards.
  • Selectable +3.3 V/+5 V single power supply (selected by VCHA pin).
  • By setting the standby pin to a low level (standby mode), circuit current can be reduced. At such times, the driver output is in a high-impedance state.
