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 pin 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 pin 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.
No Connect. These pins should always remain unconnected.
NOTES
1. PADDLE CONNECTED TO GND. THIS CONNECTION IS NOT
