GENERAL D ESCRIP TIO N  
T he AD7306 line driver/receiver is a 5 V monolithic product  
which provides an interface between T T L signal levels and dual  
standard EIA RS-232/RS-422 signal levels. T he 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.  
NC = NO CONNECT  
T he RS-232 channels are suitable for communications rates up  
to 100 kHz and the RS-422 channels are suitable for high speed  
communications up to 5 MHz. T he RS-422 transmitter comple-  
mentary outputs are closely matched and feature low timing  
skew between the complementary outputs. T his is often an es-  
sential requirement to meet tight system timing specifications.  
An internal charge pump voltage converter facilitates operation  
from a single +5 V power supply. T he internal charge pump  
generates ±10 V levels allowing RS-232 output levels to be de-  
veloped without the need for external bipolar power supplies.  
All inputs feature ESD protection, all driver outputs feature  
high source and sink current capability and are internally pro-  
tected against short circuits on the outputs. An epitaxial layer is  
used to guard against latch-up.  
A highly efficient charge pump design allows operation using  
non polarized, miniature 0.1 µF capacitors. T his gives a consid-  
erable saving in printed circuit board space over conventional  
products which can use up to 10 µF capacitors. T he charge  
pump output voltages may also be used to power external cir-  
cuitry which requires dual supplies.  
T he part is available in a 24-lead SOIC and 24-pin plastic DIP  
package.
