Pin Descriptions
PIN
FUNCTION
VCC
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.
TIN
TTL/CMOS compatible transmitter Inputs.
TOUT
±15kV ESD Protected
, RS-232 level (nominally ±5.5V) transmitter outputs.
RIN
±15kV ESD Protected
, RS-232 compatible receiver inputs.
ROUT
TTL/CMOS level receiver outputs.
ROUTB
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.
EN
Active low receiver enable control; doesn’t disable ROUTB outputs.
SHDN
Active low input to shut down transmitters and on-board power supply, to place device in low power mode.
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 power-down circuitry thereby keeping transmitters active (FORCEOFF must
be high).
