NOTE:
Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which is compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J Std-020B.

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 (Note 1).
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.
FORCEOFF Active Low to Shut Down Transmitters and On-Chip Power Supply. This overrides any automatic circuitry and FORCEON (see Table 2,
Note 1).
FORCEON Active High Input to override automatic powerdown circuitry thereby keeping transmitters active. (FORCEOFF must be high, Note 1).
NOTE:
1. These input pins incorporate positive feedback resistors. Once the input is driven to a valid logic level, the feedback resistor maintains that logic
level until VCC is removed. Unused transmitter inputs may be left unconnected by the user.
