Description
Positive and Negative Connections for Charge Pump Capacitor. 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.
Receiver Output. This outputs CMOS output logic levels.
Transmitter (Driver) Input. This input accepts TTL/CMOS levels.
Internally Generated Positive Supply (+6 V Nominal).
Power Supply Input, 3.0 V to 5.5 V.
Ground. Must be connected to 0 V.
Internally Generated Negative Supply (−6 V Nominal).
Transmitter (Driver) Output. This outputs RS-232 signal levels (typically ± 6 V).
Receiver Input. This input accepts RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected
on the input.
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.
