FUNCTION
Positive terminal of the symmetrical charge-pump capacitor C2.
Ground.
Negative terminal of the symmetrical charge-pump capacitor C2.
Regulated -4.0V or -5.5V output generated by the charge pump.
RS-232 driver output.
RS-232 driver output.
RS-232 driver output.
RS-232 receiver input.
RS-232 receiver input.
RS-232 driver output.
RS-232 receiver input.
RS-232 driver output.
Apply logic HIGH to override AUTO ON-LINE^® circuitry keeping drivers active
(SHUTDOWN must also be logic HIGH, refer to Table 2).
Apply logic LOW to shut down drivers and charge pump.
This overrides all AUTO ON-LINE^® circuitry and ONLINE (refer to Table 2).
TTL/CMOS Output indicating if a RS-232 signal is present on any Rx input.
Logic level supply voltage selection
