FUNCTION
VCC
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.
TIN
Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400k
Ω pull-up resistor to V
CC 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
Ω pull-down resistor to GND is connected to each input.
ROUT
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.
