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 V
CC
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.
