Especificações Técnicas

THE SN65176B AND SN75176B DIFFERENTIAL BUS TRANSCEIVERS ARE DESIGNED FOR BIDIRECTIONAL DATA COMMUNICATION ON MULTIPOINT BUS TRANSMISSION LINES. THEY ARE DESIGNED FOR BALANCED TRANSMISSION LINES AND MEET ANSI STANDARDS TIA/EIA-422-B AND TIA/ EIA-485-A AND ITU RECOMMENDATIONS V.11 AND X.27. THE SN65176B AND SN75176B DEVICES COMBINE A 3-STATE DIFFERENTIAL LINE DRIVER AND A DIFFERENTIAL INPUT LINE RECEIVER, BOTH OF WHICH OPERATE FROM A SINGLE 5- V POWER SUPPLY. THE DRIVER AND RECEIVER HAVE ACTIVEHIGH AND ACTIVE-LOW ENABLES, RESPECTIVELY, THAT CAN BE CONNECTED TOGETHER EXTERNALLY TO AS A DIRECTION CONTROL.   THE DRIVER DIFFERENTIAL OUTPUTS AND THE RECEIVER DIFFERENTIAL INPUTS ARE CONNECTED INTERNALLY TO FORM DIFFERENTIAL INPUT/OUTPUT (I/O) BUS PORTS THAT ARE DESIGNED TO OFFER MINIMUM LOADING TO THE BUS WHEN THE DRIVER IS DISABLED OR VCC = 0. THESE PORTS FEATURE WIDE POSITIVE AND NEGATIVE COMMON-MODE VOLTAGE RANGES, MAKING THE DEVICE SUITABLE FOR PARTYLINE APPLICATIONS.   THE DRIVER IS DESIGNED FOR UP TO 60 MA OF SINK OR SOURCE CURRENT. THE DRIVER FEATURES POSITIVE AND NEGATIVE CURRENT LIMITING AND THERMAL SHUTDOWN FOR PROTECTION FROM LINE-FAULT CONDITIONS. THERMAL SHUTDOWN IS DESIGNED TO OCCUR AT A JUNCTION TEMPERATURE OF APPROXIMATELY 150°C. THE RECEIVER FEATURES A MINIMUM INPUT IMPEDANCE OF 12 K-, AN INPUT SENSITIVITY OF ±200 MV, AND A TYPICAL INPUT HYSTERESIS OF 50 MV   ESPECIFICAÇÕES FABRICANTE: TEXAS INSTRUMENTS CATEGORIA DE PRODUTO: CI DE INTERFACE RS-422 / RS-485 ESTILO DE MONTAGEM: ORIFÍCIO DE PASSAGEM CAIXA / GABINETE: PDIP-8 SÉRIE: SN75176B FUNÇÃO: TRANSCEPTOR TAXA DE DADOS: 10MB/S NÚMERO DE MOTORISTAS: 1 DRIVER NÚMERO DE RECEPTORES: 1 RECEPTOR TENSÃO DE ALIMENTAÇÃO - MÍN: 4,75 V TENSÃO DE ALIMENTAÇÃO - MÁX: 5,25 V TENSÃO DE ALIMENTAÇÃO OPERACIONAL: 5 V CORRENTE DE ALIMENTAÇÃO OPERATIVA: 70 MA TEMPERATURA OPERACIONAL MÍNIMA: 0 C TEMPERATURA OPERACIONAL MÁXIMA: 70 C PRODUTO: TRANSCEPTORES RS422 / RS485 DUPLEX: HALF DUPLEX SN75176BP CI DE INTERFACE RS422 E RS485 DIP8 (KIT COM 5 UND) TAGS DE SN75176BP: SN65176B, CIRCUITO INTEGRADO SN75176BP, SN75176BP, SN75176, 75176, IC TRANSCEIVER HALF 1/1 8DIP, THVD1420, CI DE INTERFACE RS-422/RS-485 BUS DIFF, CI DE INTERFACE RS-422, CI RS-485, CI RS422, CI RS485, 65LBC176, SN55LBC176, DRIVER RS232, DRIVER RS485, DRIVER RS422, CI DRIVER SERIAL, SN65LBC176, DIFFERENTIAL BUS TRANSCEIVERS, DIFFERENTIAL TRANSCEIVER, BIDIRECTIONAL TRANSCEIVER, SN65LBC176Q, 01M8917, SN75LBC176, SN65LBC176P, TEXAS INSTRUMENTS, CI RS485, CI RS232, CI RS 422, SN55LBC176, SN65LBC176, SN65LBC176Q, SN75LBC176, DRIVER SERIAL, CI DE DRIVER SERIAL, SNX5176B DIFFERENTIAL BUS TRANSCEIVERS
