NEC D4721 mPD4721 UPD4721 MOC IC RS-232 LINE DRIVER/RECEIVER AT 3.3 V / 5V

Description:

The mPD4721 is a high-breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232-

E 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.

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.

• Manufacturer : NEC

• Part Number : mPD4721GS-GJG ( UPD4721 , D4721 , UPD4721GS )

• Marking : D4721

Package Included:

• 1 X NEC D4721 mPD4721 UPD4721 MOC IC RS-232 LINE DRIVER/RECEIVER AT 3.3 V / 5V
