Pin Descriptions
PIN FUNCTION
V
CC
Power Supply Input 5V ±10%.
V+ Internally generated positive supply (+10V nominal), HIN239 requires +7.5V to +13.2V.
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
Enable input. This is an active low input which enables the receiver outputs. With EN = 5V, the receiver outputs are placed
in a high impedance state.
SD Shutdown Input. With SD = 5V, the charge pump is disabled, the receiver outputs are in a high impedance state and the
transmitters are shut off.
NC No Connect. No connections are made to these leads.
HIN232, HIN236, HIN237, HIN238, HIN239, HIN240, HIN241
