DATA SHEET
MOS INTEGRATED CIRCUIT
µPD4726
RS-232 LINE DRIVER/RECEIVER
The µPD4726 is a high-voltage silicon gate CMOS line driver/receiver conforming to EIA/TIA-232-E Standards.
It contains a DC/DC converter and can operate with a +5 V single power supply. In addition, it is also provided with
ancillary functions such as a standby function.
This IC is equipped with four driver circuits and seven receiver circuits and can configure a simple RS-232 interface
circuit with only four external capacitors.
FEATURES
• Conforms to EIA/TIA-32-E (old RS-232C) Standards
• +5 V single power supply
• A standby mode can be set by making the standby pin low to reduce the power dissipation. At this time, the driver
outputs go into a high-impedance state.
• Two receiver circuits can operate as inverters without a hysteresis width even in the standby mode. The remaining
five receiver circuits are fixed to the high level.
