(RS-422/RS-423) Line Drivers with TRI-STATE® Outputs
General DescriptionThe DS1691A/DS3691arelow power SchottkyTTLline driv-
ers designedto meetthe requirementsof EIA standards
RS-422 and RS-423. They feature4 buffered outputs with
highsourceandsink currentcapability withinternal shortcir-
cuit protection.Amode controlinputprovidesa choiceofop-
eration eitheras4 single-endedline driversor2 differential
line drivers.Arisetimecontrol pinallowstheuseofan exter-
nal capacitorto slowtherise timefor suppressionof near
end crosstalkto other receiversinthe cable. Rise timeca-
pacitorsare primarily intendedfor waveshaping outputsig-
nalsinthe single-ended driver mode. Multipoint applications differential mode with waveshaping capacitorsisnotal-
lowed.
Withthe mode selectpin low,the DS1691A/DS3691are
dual-differentialline drivers with TRI-STATE outputs. They
feature ±10V output common-mode rangein TRI-STATE
mode and0V output unbalance when operated with ±5V
supply.
