Description
Power Supply Input: 5 V ± 10%.
Internally Generated Positive Supply (+9 V nominal).
Internally Generated Negative Supply (−9 V nominal).
Ground Pin. Must be connected to 0 V.
External Capacitor 1 is connected between these pins. A 0.1 µF capacitor is recommended, but larger
capacitors of up to 47 µF can be used.
External Capacitor 2 is connected between these pins. A 0.1 µF capacitor is recommended, but larger
capacitors of up to 47 µF can be used.
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels.
Transmitter (Driver) Outputs. These are RS-232 signal levels (typically ±9 V).
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is
connected on each input.
Receiver Outputs. These are CMOS output logic levels.
