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.
Active high output that indicates when the ICL32XXE is ready to transmit (i.e., V- ≤ -4V).
Active high input to override automatic powerdown circuitry thereby keeping transmitters active. (FORCEOFF must be high).
