RS-232 Receiver Inputs
TTL/CMOS Receiver Outputs
Output of the Valid Signal Detector. INVALID is enabled
high if a valid RS-232 level is present on any receiver
input.
TTL/CMOS Transmitter Inputs
Drive high to override automatic circuitry keeping
transmitters and charge pump on (FORCEOFF must be
high) (Table 1).
