DS36C278
Low Power Multipoint EIA-RS-485 Transceiver
General Description

The DS36C278isa low power differential bus/line trans-
ceiver designedto meet the requirementsof RS-485 stan-
dardfor multipoint data transmission.In additionitis com-
patible with TIA/EIA-422-B.
The CMOS design offers significant power savings overits
bipolar and ALS counterparts without sacrificing ruggedness
against ESD damage. The deviceis idealfor usein battery
poweredor power conscious applications. ICCis specifiedat
500µA maximum.
The driver and receiver outputs feature TRI-STATE® capa-
bility. The driver outputs operate over the entire common
mode rangeof −7Vto +12V. Bus contentionor fault situa-
tions that cause excessive power dissipation within the de-
viceare handledbya thermal shutdown circuit, which forces
the driver outputs intothe high impedance state.
The receiver incorporatesafail safe circuit which guarantees high output state whenthe inputs areleft open. (Note1)
The DS36C278Tis fully specified over the industrial tem-
perature range (−40˚Cto +85˚C).
