Pin Descriptions

FUNCTION

VCC

System power supply input (2.7V to 5.5V).

V+

Internally generated positive transmitter supply (+5.5V).

V-

Internally generated negative transmitter supply (-5.5V).

GND

Ground connection. This is also the potential of the thermal pad (PD).

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)

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).

FORCEON

Active high input to override automatic power-down circuitry thereby keeping transmitters active. (FORCEOFF must be high).

NC

No Connection

PD

Exposed Thermal Pad. Connect to GND.

NOTE: ISL4238E 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.
