Function
Internally Generated Positive Supply (+9 V nominal). A 0.1 F capacitor must be connected
between this pin and GND.
External Capacitor 1 Terminals. A 0.1 F capacitor must be connected between these pins.
RS-232 Receiver R2 Input. This input accepts RS-232 input voltages.
RS-232 Transmitter (Driver) T1 Output (Typically 7.5 V).
RS-232 Transmitter (Driver) T2 Output (Typically 7.5 V).
Power Supply Input (5 V
RS-422 Receiver R1, Differential Input B.
Receiver R1 Input. May be configured to accept either single ended RS-232 levels or
differential RS-422 levels. It is configured using the 232/422 SEL pin.
RS-422 Transmitter (Driver) T3, Differential Output B.
RS-232 Transmitter (Driver) T3, Differential Output A.
No Connect Pins.
Ground Pin. Must be connected to 0 V.
Select Input. This input configures Receiver R1 to accept either RS-232 or RS-422 signal lev-
els. A Logic 1 on this input selects 232 operation while a Logic 0 selects 422 operation.
TTL/CMOS Input to the RS-422 Transmitter T3.
TTL/CMOS Output from Receiver R1.
TTL/CMOS Input to RS-232 Transmitter T2.
TTL/CMOS Input to RS-232 Transmitter T1.
TTL/CMOS Output from Receiver R2.
External Capacitor 2 Terminals. A 0.1 F capacitor must be connected between these pins.
Internally Generated Negative Supply (–9 V nominal). A 0.1 F capacitor must be connected
between this pin and GND.
