5 / 17 page ST3243B ST3243C Pin configuration Doc ID 7539 Rev 10 5/17 14 T1IN First transmitter input voltage 15 R5OUT Fifth receiver output voltage 16 R4OUT Fourth receiver output voltage 17 R3OUT Third receiver output voltage 18 R2OUT Second receiver output voltage 19 R1OUT First receiver output voltage 20 R2OUTB Non-inverting complementary receiver output, always active for wake-up 21 INVALID Output of the valid signal detector. Indicates if a valid RS-232 level is present on receiver inputs logic “1” 22 FORCEOFF Drive low to shut down transmitters and on-board power supply. This overrides all automatic circuitry and FORCEON 23 FORCEON Drive high to override automatic circuitry keeping transmitters on (FORCEOFF must be high) 24 C1- Negative terminal of voltage-charge pump capacitor 25 GND Ground 26 VCC Supply voltage 27 V+ 5.5 V generated by the charge pump 28 C1+ Positive terminal of voltage-charge pump capacitor Table 2. Pin description (continued) Pin n° Symbol Name and function Table 3. Truth table FORCEOFF TOUT ROUT R2OUTB 0 HIGH Z HIGH Z ACTIVE(1) 1ACTIVE(1) ACTIVE(1) ACTIVE(1) 1. If the part is in auto-power-down mode (FORCEOFF = VCC, FORCEON = GND) it is shutdown, if no valid RS-232 levels are present on all receiver input. |
