LINEAR INTEGRATED CIRCUIT  
MULTIPLE RS-232 DRIVERS  
AND RECEIVERS  
„
DESCRIPTION  
The UTC 75323 provides a rugged, low-cost effectiveness  
performance due to the circuits consisting of bipolar ones,  
incorporating five drivers and three receivers. It is characterized  
with less required external components, board spaces and an easy  
interface between UART and serial-port connector for a single chip.  
Working at temperatures from 0℃ to 70℃ is one of its features.  
„
FEATURES  
* Single chip with easy interface between UART and serial-port  
connector  
* Data rates : 20 kb/s.  
* Complement to the UTC 75232.

Note: 1. The algebraic convention, where the more positive(less negative) limit is designated as maximum, is used in  
this data sheet for logic levels only, e. g.,if-10V is maximum, the typical value is a more negative voltage.  
2. Output short-circuit conditions must maintain the total power dissipation below absolute maximum ratings.  
3. Test conditions are those specified by TIA/EIA-232-F and as listed above.

APPLICATION INFORMATION  
Diodes placed in series with the VDD and VSS leads protect the UTC 75323 in the fault condition in which the  
device output are shorted to VDD or VSS, and the Power supplies are at low and provide low-impedance paths to  
ground (see Figure7)

*See Figure Slew Rate vs. Load Capacitance to select the correct values for the loading capacitors (C1, C2, C3, C4  
and C5), which may be required to meet the RS-232 maximum slew-rate requirement of 30V/us. The value of the  
loading capacitors resrequired depends upon the line length and desired slew rate, but is typically 330pF.  
Note C: To use the receivers only, VDD and Vss both must be powered or tied to ground.
