The TRS3232 device is designed to convert single-ended signals into RS232-compatible signals, and vice-versa.
This device can be used in any application where an RS232 line driver or receiver is required. One benefit of this device is its ESD protection, which helps protect other components on the board when the RS232 lines are tied to a physical connector.
VCC | C1 | C2, C3, and C4 |
---|---|---|
3.3 V ± 0.3 V | 0.1 µF | 0.1 µF |
5 V ± 0.5 V | 0.047 µF | 0.33 µF |
3 V to 5.5 V | 0.1 µF | 0.47 µF |
For proper operation, add capacitors as shown in Figure 9 and Table 4.
ROUT and DIN connect to UART or general purpose logic lines. FORCEON and FORCEOFF may 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 RS232 connector or cable. DIN, FORCEON, and FORCEOFF inputs must not be left unconnected.
