MAX149415kVRMSIsolated 20Mbps Half-Duplex PROFIBUS/RS-485 Transceivers with ±35kV ESD Protection | Digital Isolators | 2 | Active | The MAX14941/MAX14942 isolated RS-485/PROFIBUS-DP transceivers provide 5000VRMS(60s) of galvanic isolation between the cable-side (RS-485 driver/receiver-side) and the UART-side of the device. Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 20Mbps.An integrated LDO provides a simple and space-efficient architecture for providing power to the cable side of the IC.Each device includes one half-duplex driver/receiver channel. The receiver is 1/4-unit load, allowing up to 128 transceivers on a common bus.Integrated true fail-safe circuitry ensures a logic-high on the receiver output when inputs are shorted or open. Undervoltage lockout disables the driver when cable-side or UART-side power supplies are below functional levels.The driver outputs/receiver inputs are protected from ±35kV electrostatic discharge (ESD) to GNDB on the cable side, as specified by the Human Body Model (HBM).The MAX14941/MAX14942 are available in a wide-body 16-pin SOIC package and operate over the -40°C to +105°C temperature range.ApplicationsHVACIndustrial Automation EquipmentPower MetersProgrammable Logic Controllers |

MAX14954Ruggedized Quad PCIe Redriver with Equalization and Extended Temperature Operation | Signal Buffers, Repeaters, Splitters | 2 | Active | The MAX14954 is a quad equalizer/redriver designed to improve PCI Express®(PCIe) signal integrity by providing programmable input equalization at its receiver and programmable redrive circuitry. The output circuitry re-establishes deemphasis lost on the board and compensates for circuit-board loss. The device permits optimal placement of key PCIe components. The device is useful with stripline, microstrip printed circuits, and balanced 100Ω cable.The device is tailored for PCIe and features electrical idle and receiver detection on each channel. It is optimized for PCIe Gen III (8.0GT/s) and Gen II (5.0GT/s) data rates, while still handling Gen I (2.5GT/s).The MAX14954 is available in a small, lead-free, 42-pin (3.5mm x 9.0mm) TQFN package for optimal layout and minimal space requirements. The device is specified over -40°C to +85°C extended operating temperature range.ApplicationsCarrier BoardsComputer on ModulesIndustrial/Embedded PCMedical EquipmentRack Server Industrial PCsTest Equipment |
