TTL/CMOS compatible transmitter Inputs.

±15kV ESD Protected, RS-232 level (nominally ±5.5V) transmitter outputs.

±15kV ESD Protected, RS-232 compatible receiver inputs.

TTL/CMOS level receiver outputs.

TTL/CMOS level, noninverting, always enabled receiver outputs.

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).
