FUNCTION

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.

Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400k

Transmitter Outputs. These are RS-232 levels (nominally

±10V).

Receiver Inputs. These inputs accept RS-232 input levels. An internal 5k

Ω pull-down resistor to GND is connected to each input.

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.
