FUNCTION

Power Supply Input 5V ±10%, (5V ±5% HIN207A).

Internally generated positive supply (+10V nominal).

Internally generated negative supply (-10V nominal).

Ground Lead. Connect to 0V.

External capacitor (+ terminal) is connected to this lead.

External capacitor (- terminal) is connected to this lead.

External capacitor (+ terminal) is connected to this lead.

External capacitor (- terminal) is connected to this lead.

Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kΩ pull-up resistor to VCC is connected to each lead.

Transmitter Outputs. These are RS-232 levels (nominally ±10V).

Receiver Inputs. These inputs accept RS-232 input levels. An internal 5kΩ pull-down resistor to GND is connected to each input.

Receiver Outputs. These are TTL/CMOS levels.

Enable Input. This is an active low input which enables the receiver outputs. With EN = 5V, the outputs are placed in a high

impedance state.

Shutdown Input. With SD = 5V (HIN213A SD = 0V), the charge pump is disabled, the receiver outputs are in a high impedance

state (except R4 and R5 of HIN241A) and the transmitters are shut off.

No Connect. No connections are made to these leads.
