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 input to override automatic power-down circuitry thereby keeping transmitters active. (FORCEOFF must be high).
Active low receiver enable control.
Active low input to shut down transmitters and on-board power supply, to place device in low power mode.
No Connection
Exposed Thermal Pad. Connect to GND.
