PIN FUNCTION
V
CC
Power Supply Input 5V 10%, (5V 5% HIN207E).
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 400k 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 5k pull-down resistor to GND is connected to each input.
R
OUT
Receiver Outputs. These are TTL/CMOS levels.
EN, EN Receiver Enable Input. With EN = 5V (HIN213E EN=0V), the receiver outputs are placed in a high impedance state.
SD, SD Shutdown Input. With SD = 5V (HIN213E SD = 0V), the charge pump is disabled, the receiver outputs are in a high impedance
state (except R4 and R5 of HIN213E) and the transmitters are shut off.
NC No Connect. No connections are made to these leads.
