with a 0.1µF ceramic capacitor.

GND: Ground Pin.

2V. This pin requires an external capacitor C = 0.1µF for

charge storage. The capacitor may be tied to ground or

a common capacitor. For large numbers of devices, in-

creasing the size of the shared common storage capaci-

tors is recommended to reduce ripple.

– 2V). This pin requires an external capacitor C = 0.1µF for

charge storage.

pins require two external capacitors C = 0.1µF: one from

charge pump efficiency, the capacitor’s effective series

resistance should be less than 2Ω.

TR IN: RS232 Driver Input Pins. Inputs are TTL/CMOS

compatible. The inputs of unused drivers can be left

included on chip.

TR OUT: Driver Outputs at RS232 Voltage Levels. The

driver outputs are protected against ESD to ±10kV for

human body model discharges.

RX IN: Receiver Inputs. These pins can be forced to ±25V

without damage. The receiver inputs are protected against

ESD to ±10kV for human body model discharges. Each

receiver provides 0.4V of hysteresis for noise immunity.

RX OUT: Receiver Outputs with TTL/CMOS Voltage

Levels.
