Pin Descriptions
PIN
FUNCTION
V
CC
System power supply input (3.0V to 5.5V).
V+
Internally generated positive transmitter supply (+5.5V).
V-
Internally generated negative transmitter supply (-5.5V).
GND
Ground connection.
C1+
External capacitor (voltage doubler) is connected to this lead.
C1-
External capacitor (voltage doubler) is connected to this lead.
C2+
External capacitor (voltage inverter) is connected to this lead.
C2-
External capacitor (voltage inverter) is connected to this lead.
T
IN
TTL/CMOS compatible transmitter Inputs.
T
OUT
RS-232 level (nominally
±
5.5V) transmitter outputs.
R
IN
RS-232 compatible receiver inputs.
R
OUT
TTL/CMOS level receiver outputs.
R
OUTB
TTL/CMOS level, noninverting, always enabled receiver outputs.
INVALID
Active low output that indicates if no valid RS-232 levels are present on any receiver input.
READY
Active high output that indicates when the ICL32XXE is ready to transmit (i.e., V-
≤
-4V)
FORCEOFF Active low to shut down transmitters and on-chip power supply. This overrides any automatic circuitry and FORCEON (see Table 2).
FORCEON
Active high input to override automatic powerdown circuitry thereby keeping transmitters active. (FORCEOFF must be high).
