1993 data sheet mos integrated circuit m pd4723 document no. s12200ej2v0ds00 (2nd edition) (previous no. ic-3284) date published january 1997 n printed in japan rs-232 line driver/receiver at 3.3 v/5 v the m pd4723 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, allowing it to operate with a single +3.3 v or +5 v power supply. it also provides standby function. this ic incorporates 3 driver circuits and 3 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 v cha 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. ? even in the standby mode, 2 receiver circuits can operate as inverters without hysteresis width. the other circuit is fixed at a high level. ordering information part number package m pd4723gs-gjg 30-pin plastic ssop (300 mil)
