PIN FUNCTION DESCRIPTION
Mnemonic
Function
VCC
Power Supply Input 5 V
± 10%.
V+
Internally Generated Positive Supply (+10 V nominal).
V–
Internally Generated Negative Supply (–10 V nominal).
GND
Ground Pin. Must be connected to 0 V.
C1+
ADM202 External Capacitor, (+ terminal) is connected to this pin.
ADM203: The capacitor is connected internally and no external capacitor is required.
C1–
ADM202 External Capacitor, (– terminal) is connected to this pin.
ADM203: The capacitor is connected internally and no external capacitor is required.
C2+
ADM202 External Capacitor, (+ terminal) is connected to this pin.
ADM203: The capacitor is connected internally and no external capacitor is required.
C2–
ADM202 External Capacitor, (– terminal) is connected to this pin.
ADM203: The capacitor is connected internally and no external capacitor is required.
TIN
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 k
pull-up resistor to VCC is
connected on each input.
TOUT
Transmitter (Driver) Outputs. These are RS-232 levels (typically
±10 V).
RIN
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 k
pull-down resistor to GND is
connected on each of these inputs.
ROUT
Receiver Outputs. These are TTL/CMOS levels.
