LocalTalk™ Dual Driver/Triple Receiver
General DescriptionThe DS8935isa dual driver/triple receiver device optimized providea single chip solutionfora LocalTalk Interface.
The device providesone differential TIA/EIA-422 driver,one
TIA/EIA-423 single ended driver, one TIA/EIA-422 receiver
andtwo TIA/EIA-423receivers,allina surfacemount 16-pin
package.This deviceis electrically similar tothe 26LS30and
26LS32 devices.
The drivers feature ±10V common mode range,andthedif-
ferential driverprovides TRI-STATEable outputs.The receiv-
ers offer ±200mV thresholds overthe ±10V common mode
range.
The device offers enable circuitryforthe differential driver
and selectable enablingforthe three receivers.
Features Single chip solutionfor LocalTalkport Two driver/three receiversper package Wide common mode range: ±10V ±200mV receiver sensitivity70mV typical receiver input hysteresis Availablein SOIC packaging Failsafe receiverfor open inputs
