Pin No. Mnemonic Description

1, 3

C1+, C1– External Capacitor 1 is connected between these pins. A 0.1 μF capacitor is recommended, but larger capacitors

of up to 47 μF can be used.

2

V+

Internally Generated Positive Supply (6 V Nominal).

4, 5

C2+, C2– External Capacitor 2 is connected between these pins. A 0.1 μF capacitor is recommended, but larger capacitors

of up to 47 μF can be used.

6

V–

Internally Generated Negative Supply (−6 V Nominal).

7, 14

T2OUT, T1OUT Transmitter (Driver) Outputs. These are RS-232 signal levels (typically ±6 V).

8, 13

R2IN, R1IN Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected

on each input.

9, 12

R2OUT, R1OUT Receiver Outputs. These are TTL/CMOS output logic levels.

10, 11

T2IN, T1IN

Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels.

15

GND

Ground Pin. Must be connected to 0 V.

16

VCC

Power Supply Input (3.3 V ± 0.3 V).
