8.1.1 Typical Application

ROUT and DIN connect to UART or general purpose logic lines. FORCEON and FORCEOFFmay be connected general purpose logic lines or tied to ground or VCC. INVALID may be connected to a general purpose logic line or left unconnected. RIN and DOUT lines connect to a RS-232 connector or cable. DIN, FORCEON, and FORCEOFF inputs must not be left unconnected.

TRSF3221E Typical Operating Circuit and Capacitor Values
A. C3 can be connected to VCC or GND.
B. Resistor values shown are nominal.
C. Nonpolarized ceramic capacitors are acceptable. If polarized tantalum or electrolytic capacitors are used, they must be connected as shown.
