C1+, C1鈥�
External Capacitor 1 is connected between these pins. A 0.1 渭F capacitor is recommended, but larger capacitors
of up to 47 渭F can be used.
2
V+
Internally Generated Positive Supply (6 V Nominal).

C2+, C2鈥�
External Capacitor 2 is connected between these pins. A 0.1 渭F capacitor is recommended, but larger capacitors
of up to 47 渭F can be used.
6
V鈥�
Internally Generated Negative Supply (6 V Nominal).
7, 14
T2OUT, T1OUT
Transmitter (Driver) Outputs. These are RS-232 signal levels (typically 卤6 V).
8, 13
R2IN, R1IN
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 k惟 pull-down resistor to GND is connected
on each input.
9, 12
R2OUT, R1OUT
Receiver Outputs. These are TTL/CMOS output logic levels.
10, 11
T2IN, T1IN
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels.
15
GND
Ground Pin. Must be connected to 0 V.
16
VCC
Power Supply Input (3.3 V 卤 0.3 V).
