2 Pinout ISL83387E (TSSOP) TOP VIEW C1+ V+ C1- C2+ C2- V- T1IN T2IN INVALID FORCEON R3OUT FORCEOFF GND T1OUT T2OUT T3OUT R2IN VL R1OUT R2OUT VCC R1IN R3IN 24 23 22 21 20 19 18 17 16 15 14 13 1 2 3 4 5 6 7 8 9 10 11 12 T3IN Pin Descriptions PIN FUNCTION VCC System power supply input (3.0V 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. The switching point is a function of the VL voltage. 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. Swings between GND and VL. VL Logic-Level Supply. All TTL/CMOS inputs and outputs are powered by this supply. INVALID Active low output that indicates if no valid RS-232 levels are present on any receiver input. Swings between GND and VL. FORCEOFF Active low to shut down transmitters and on-chip power supply. This overrides any automatic circuitry and FORCEON (see Table 2). The switching point is a function of the VL voltage. FORCEON Active high input to override automatic powerdown circuitry thereby keeping transmitters active. (FORCEOFF must be high). The switching point is a function of the VL voltage. ISL83387E |
