3 / 14 page 3 FN6045.3 February 13, 2008 Pin Descriptions PIN FUNCTION VCC System power supply input (2.7V to 5.5V). V+ Internally generated positive transmitter supply (+5.5V). V- Internally generated negative transmitter supply (-5.5V). GND Ground connection. C1+ External capacitor (voltage doubler) is connected to this lead. C1- External capacitor (voltage doubler) is connected to this lead. C2+ External capacitor (voltage inverter) is connected to this lead. C2- External capacitor (voltage inverter) is connected to this lead. TIN TTL/CMOS compatible transmitter Inputs. TOUT ±15kV ESD Protected, RS-232 level (nominally ±5.5V) transmitter outputs. RIN ±15kV ESD Protected, RS-232 compatible receiver inputs. ROUT TTL/CMOS level receiver outputs. INVALID Active low output that indicates if no valid RS-232 levels are present on any receiver input. FORCEOFF Active low to shut down transmitters and on-chip power supply. This overrides any automatic circuitry and FORCEON (see Table 2). FORCEON Active high input to override automatic power-down circuitry thereby keeping transmitters active. (FORCEOFF must be high). EN Active low receiver enable control.
