TTL/CMOS compatible transmitter Inputs.
RS-232 level (nominally ±5.5V) transmitter outputs.
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.
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.
Active high input to override automatic powerdown circuitry thereby keeping transmitters active. (FORCEOFF must be high).
