FORCEON
Drive high to override automatic circuitry, keeping transmitter and charge pump on.
FORCEOFF must be high (Table 1).

TIN
TTL/CMOS Transmitter Input
10
INVALID
Output of the Invalid Signal Detector. INVALID is pulled low if no valid RS-232 level is present on
the receiver input.

FORCEOFF
Force-Off Input, active low. Drive low to shut down transmitter, receiver, and on-board charge
pump. This overrides all automatic circuitry and FORCEON (Table 1).
