Ground Pin. Must Be Connected to 0 V.
External Capacitor 1 is connected between
these pins. 0.1

F capacitor is recommended
but larger capacitors up to 47
μ
F may be used.
External Capacitor 2 is connected between
these pins. 0.1

T ransmitter (Driver) Inputs. T hese inputs ac-
cept T T L/CMOS levels.
T ransmitter (Driver) Outputs. T hese are RS-
232 signal levels (typically
±
9 V).
Receiver Inputs. T hese inputs accept RS-232
signal levels. An Internal 5 k
pull-down resis-
tor to GND is connected on each input.
Receiver Outputs. T hese are CMOS output
logic levels.
