VCC (Pin 16) Power supply pin for the device, +5V (±10% ). V+ (Pin 2) Positive supply for EIA/TIA-232-E drivers. Recommended external capacitor: C4= 0.1 µF (≥ 6.3V). Capacitor value should not be less than 0.1 µF. This supply is not intended to be loaded externally. (Note 9) V − (Pin 6) Negative supply for EIA/TIA-232-E drivers. Recommended external capacitor: C3= 0.1 µF (≥ 16V). Capacitor value should not be less than 0.1 µF. This supply is not intended to be loaded externally. (Note 9) C1+, C1− (Pins 1, 3) External capacitor connection pins. Recommended capaci- tor: C1 = 0.1 µF (≥ 6.3V). Capacitor value should not be less than 0.1 µF. (Note 9) C2+, C2− (Pins 4, 5) External capacitor connection pins. Recommended capaci- tor: C2 = 0.1 µF (≥ 16V). Capacitor value should not be less than 0.1 µF. (Note 9) D IN1, DIN2 (Pins 11, 10) Driver input pins are TTL/CMOS compatible. Inputs of un- used drivers may be left open, an internal active pull-up re- sistor (500 kΩ minimum, typically 1 MΩ ) pulls input HIGH. Output will be LOW for input pins. D OUT 1, DOUT 2 (Pins 14, 7) Driver output pins conform to EIA/TIA-232-E levels. R IN1, RIN2 (Pins 13, 8) Receiver input pins accept EIA/TIA-232-E input voltages (±25V). Receivers feature guaranteed hysteresis of 200 mV. Unused receiver input pins may be left open. Internal input resistor (5 kΩ ) pulls input LOW, providing a fail-safe HIGH output. R OUT 1, ROUT 2 (Pins 12, 9) Receiver output pins are TTL/CMOS compatible. Receiver output HIGH voltage is specified for both CMOS and TTL load conditions. GND (Pin 15) Ground Pin. Note 9:All capacitor values have tolerances of less than±20% . Typical Application Information DS012622-7 PrintDate=1998/06/22 PrintTime=10:23:03 42589 ds012622 Rev.
