GENERAL DESCRIPTION

The AD7306 line driver/receiver is a 5 V monolithic product which provides an interface between TTL signal levels and dual standard EIA RS-232/RS-422 signal levels. The part contains two RS-232 drivers, one RS-422 driver, one RS-232 receiver,
and one receiver path which can be configured either as RS-232 or as RS-422.
An internal charge pump voltage converter facilitates operation from a single +5 V power supply. The internal charge pump generates ±10 V levels allowing RS-232 output levels to be developed without the need for external bipolar power supplies.
A highly efficient charge pump design allows operation using non polarized, miniature 0.1 mF capacitors. This gives a considerable saving in printed circuit board space over conventional products which can use up to 10 mF capacitors. The charge pump output voltages may also be used to power external circuitry
which requires dual supplies.
