External Capacitor C1 is connected between these pins; a 0.1 μF capacitor is recommended, but larger capacitors up to 10 μF can be used. 2 4 ROUT Receiver Output. This pin outputs CMOS output logic levels. 3 5 TIN Transmitter (Driver) Input. This input accepts TTL/CMOS levels. 4 7 V+ Internally Generated Positive Supply (+6 V Nominal). 5 8 VCC Power Supply Input, 3.0 V to 5.5 V. 6 9 GND Ground. Must be connected to 0 V. 7 10 V– Internally Generated Negative Supply (−6 V Nominal). 8 12 TOUT Transmitter (Driver) Output. This pin outputs RS-232 signal levels (typically ±6 V). 9 13 RIN Receiver Input. This input accepts RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected on the input. 10, 11 15, 16 C2−, C2+ Positive and Negative Connections for Charge Pump Capacitor. External Capacitor C2 is connected between these pins; a 0.1 μF capacitor is recommended, but larger capacitors up to 10 μF can be used. N/A 3, 6, 11, 14 NC No Connect. These pins should always remain unconnected. |
