Inkcazo
I-SN75176A idibanisa umqhubi we-3-state differential line kunye ne-receiver input line receiver, zombini ezo zisebenza kumbane omnye we-5-V.Umqhubi kunye nomamkeli banemisebenzi esebenzayo-phezulu kwaye esebenzayo ephantsi yenza, ngokulandelelanayo, enokudityaniswa ngaphandle kunye ukuze isebenze njengolawulo lwesikhokelo.Iziphumo zomahluko womqhubi kunye nezimvo zomamkeli owahlukileyo ziqhagamshelwe ngaphakathi ukwenza umahluko igalelo/imveliso (I/O) izibuko zebhasi ezilungiselelwe ukunika ukulayisha okuncinci kwibhasi nanini na umqhubi ekhubazekile okanye iVCC = 0. La mazibuko abonisa ububanzi obulungileyo kunye neendidi zamandla ombane zemo yesiqhelo engalunganga eyenza isixhobo silungele usetyenziso lwalayini yeqela.Umqhubi wenzelwe ukuphatha imithwalo ukuya kwi-60 mA yesinki okanye umthombo wangoku.Umqhubi ubonisa i-positive- kunye ne-negative-current limiting kunye nokuvalwa kwe-thermal ukhuseleko kwiimeko zempazamo zomgca.Ukuvalwa kweThermal kuyilelwe ukuba kwenzeke kwindawo ekudityanwa kuyo iqondo lobushushu elimalunga ne-150°C.Umamkeli ubonisa i-impedance encinci ye-12 kΩ, i-input sensitivity ye-± 200 mV, kunye ne-hysteresis yegalelo eliqhelekileyo le-50 mV.I-SN75176A ingasetyenziswa kwizicelo zemigca yothumelo eqasha i-SN75172 kunye ne-SN75174 yabaqhubi bemigca ephindwe kane kunye ne-SN75173 kunye ne-SN75175 yabamkeli bemigca ephindwe kane.I-SN75176A ibonakaliswe ukusebenza ukusuka kwi-0 ° C ukuya kwi-70 ° C.
