PIN DESCRIPTIONS
Pin Number Pin Name Pin Function
1, 3 C1+, C1− External capacitor connection pins. Recommended external capacitor C1 = 0.1μF (6.3V)
2 V+ Positive supply for TIA/EIA-232E drivers. Recommended external capacitor C4 = 0.1μF (6.3V)
4, 5 C2+, C2− External capacitor connection pins. Recommended external capacitor C2 = 0.1μF (16V)
6 V− Negative supply for TIA/EIA-232E drivers. Recommended external capacitor C3 = 0.1μF (16V)
7, 14 T1out, T2out Transmitter output pins conform to TIA/EIA-232E levels. The typical transmitter output swing is ±8V
when loaded 3kΩ load to ground. The open-circuit output voltage swings from (V+ − 0.6V) to V−
8,13 R1in, R2in Receiver inputs accept TIA/EIA-232
9, 12 R1out and R2out Receiver output pins are TTL/CMOS compatible
10, 11 Tin1, Tin2 Transmitter input pins are TTL/CMOS compatible. Inputs of transmitter do not have pull-up resistors.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
