FUNCTION
Receiver Enable. Apply logic LOW for normal operation. Apply logic HIGH to
disable the receiver outputs (high-Z state).
Positive terminal of the voltage doubler charge-pump capacitor.
Regulated +5.5V output generated by the charge pump.
Negative terminal of the voltage doubler charge-pump capacitor.
Positive terminal of the inverting charge-pump capacitor.
Negative terminal of the inverting charge-pump capacitor.
Regulated -5.5V output generated by the charge pump.
RS-232 driver output.
RS-232 receiver input.
TTL/CMOS receiver output.
TTL/CMOS Output indicating online and shutdown status.
TTL/CMOS driver input.
TTL/CMOS driver input.
Apply logic HIGH to override AUTO ON-LINE^® circuitry keeping drivers active
(SHUTDOWN must also be logic HIGH, refer to Table 2).
R₁OUT
TTL/CMOS receiver output.
