FUNCTION
VCC
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.
TIN
Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400k
pull-up resistor to VCC is connected to each lead.
TOUT
Transmitter Outputs. These are RS-232 levels (nominally
±10V).
RIN
Receiver Inputs. These inputs accept RS-232 input levels. An internal 5k
pull-down resistor to GND is connected to each input.
ROUT
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.
