Texas Instruments (SN75LBC184P) Transceiver RS485, ± 15kV ESD Protected

roduct OverviewThe SN75LBC184P is a Differential Data Line Transceiver in the trade-standardfootprint of the SN75176 with built-in protection against high-energy noisetransients. This feature provides a substantial increase in reliability forbetter immunity to noise transients coupled to the data cable over most existingdevices. Use of these circuits provides a reliable low-cost direct-coupled (withno isolation transformer) data line interface without requiring any externalcomponents. The SN75LBC184P can withstand overvoltage transients of 400W peak(typical). The conventional combination wave called out in IEC 61000-4-5simulates the overvoltage transient and models a unidirectional surge caused byovervoltage from switching and secondary lightning transients. ESD protectionfor bus terminals exceeds, ±30kV IEC 61000-4-2 contact discharge, ±15kV IEC61000-4-2 air-gap discharge and ±15kV EIA/JEDEC human body model.Integrated transient voltage suppressionCircuit damage protection of 400W peak (typical) per IEC 61000-4-5Controlled driver output-voltage slew rates allow longer cable stub lengths250kbps in electrically noisy environmentsOpen-circuit fail-safe receiver design1/4 Unit load allows for 128 devices connected on busThermal shutdown protectionPower-up and power-down glitch protectionEach transceiver meets/exceeds requirements of TIA/EIA-485 (RS-485) & ISO/IEC8482:1993(E) standards300µA Maximum low disabled supply currentApplicationsIndustrial, Communications & Networking, Metering, Motor Drive & ControlProduct InformationDevice Type: RS485 TransceiverIC Interface Type: RS485No. of Drivers: 1DriversNo. of Receivers: 1ReceiversSupply Voltage Min: 4.75VSupply Voltage Max: 5.25VDriver Case Style: DIPNo. of Pins: 8PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: -
