8.2 Typical Application

ROUT and DIN connect to UART or general-purpose logic lines. RIN and DOUT lines connect to a RS232 connector or cable. For proper operation, add capacitors as shown in Table 8-1.

TRS3232E Typical Operating Circuit and Capacitor Values
A. C3 can be connected to VCC or GND
Resistor values shown are nominal.
Nonpolorized ceramic capacitors are acceptable. If polarized tantalum or electrolytic capacitors are used, they should be connected as shown.
