Pin Descriptions
PIN FUNCTION
V
CC
Power Supply Input 5V ±10%.
V+ Internally generated positive supply (+10V nominal).
V- Internally generated negative supply (-10V nominal).
GND Ground Lead. Connect to 0V.
C1+ External capacitor (+ terminal) is connected to this lead.
C1- External capacitor (- terminal) is connected to this lead.
C2+ External capacitor (+ terminal) is connected to this lead.
C2- External capacitor (- terminal) is connected to this lead.
T
IN
Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kΩ pull-up resistor to V
CC
is connected to each lead.
T
OUT
Transmitter Outputs. These are RS-232 levels (nominally ±10V).
R
IN
Receiver Inputs. These inputs accept RS-232 input levels. An internal 5kΩ pull-down resistor to GND is connected to each input.
R
OUT
Receiver Outputs. These are TTL/CMOS levels.
