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 low receiver enable control; doesn’t disable R
Active low input to shut down transmitters and on-board power supply, to place device in low power mode.
FORCEON (see Table 2).
Active high input to override automatic power-down circuitry thereby keeping transmitters active (FORCEOFF must
be high).
