Transmitter Input(s)
+5.5V/+4.0V Generated by Charge Pump. If charge pump is generating +4.0V, the part
has switched from RS-232 compliant to RS-232 compatible mode.
No Connection. These locations are not populated with solder bumps.
FORCEON Input, Active-High. Drive FORCEON high to override automatic circuitry,
keeping transmitters and charge pumps on. Pulls itself high internally if not connected.
No Connection. These locations are populated with solder bumps, but are electrically
isolated.
