The MAX14878–MAX14880 family of high-speed transceivers improve communication and safety by integrating galvanic isolation between the CAN protocol controller side of the device and the physical wires of the network (CAN) bus. Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports. The MAX14879 provides up to 2750VRMS(60s) of galvanic isolation, while the MAX14878/MAX14880 provide up to 5000VRMS(60s) of galvanic isolation in 8-pin and 16-pin SOIC packages.All transceivers operate up to the maximum high-speed CAN data rate of 1Mbps. The MAX14879/MAX14880 feature an integrated standby input (STB) on the isolated side of the transceiver to disable the driver and place the transceiver in a low-power standby mode. The MAX14878 does not include the standby input.The MAX14878–MAX14880 transceivers feature integrated protection for robust communication. The receiver input common-mode range is ±25V, exceeding the ISO 11898 specification of -2V to +7V, and are fault tolerant up to ±54V. Driver outputs/receiver inputs are also protected from ±15kV electrostatic discharge (ESD) to GNDB on the bus side, as specified by the Human Body Model (HBM).Interfacing with CAN protocol controllers is simplified by the wide 1.71V to 5.5V supply voltage range (VDDA) on the controller side of the device. This supply voltage sets the interface logic levels between the transceiver and controller. The supply voltage range for the CAN bus side of the device is 4.5V to 5.5V (VDDB).The MAX14878–MAX14880 are available in a wide-body 16-pin SOIC package with 8mm of creepage and clearance. The MAX14878 is also available in 8-pin wide-body SOIC packages with 5mm (MAX14878) and 8mm (MAX14878W) creepage. All devices operate over the -40°C to +125°C temperature range.ApplicationsBuilding AutomationHVACIndustrial ControlsSwitching Gear

The MAX481E, MAX483E, MAX485E, MAX487E- MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electro-static discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw as little as 120µA supply current when unloaded or when fully loaded with disabled drivers (see Selector Guide). Additionally, the MAX481E, MAX483E, and MAX487E have a low-current shutdown mode in which they consume only 0.5µA. All parts operate from a single +5V supply.Drivers are short-circuit current limited, and are protected against excessive power dissipation by thermal shutdown circuitry that places their outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487E and MAX1487E feature quarter-unit-load receiver input impedance, allowing up to 128 transceivers on the bus. The MAX488E-MAX491E are designed for full-duplex communications, while the MAX481E, MAX483E, MAX485E, MAX487E, and MAX1487E are designed for half-duplex applications. For applications that are not ESD sensitive see the pinand function-compatible MAX481, MAX483, MAX485, MAX487-MAX491, and MAX1487.ApplicationsIndustrial-Control Local Area NetworksLevel TranslatorsLow-Power RS-422 TransceiversLow-Power RS-485 TransceiversTransceivers for EMI-Sensitive Applications

The MAX14883E fault-protected, high-speed Control Area Network (CAN) transceiver is optimized for industrial network applications. This device features ±60V fault protection, a ±25V functional common mode input range, and high ±10kV ESD protection (contact discharge) on the CANH and CANL bus. The device operates from a single 5V supply (VCC) and includes a logic-level supply input (VL) for interfacing with 1.8V to 5V logic.The MAX14883E features a polarity selection input (POL) that swaps the CANH and CANL I/Os, allowing for software correction of cross-wired field cables.The MAX14883E operates at the maximum CAN high-speed data rate, allowing up to 1Mbps on small networks. The maximum speed on large networks may be limited by capacitive loading and other factors.The transceiver includes a transmitter dominant timeout (tDOM) to prevent bus lockup caused by controller error or by a fault on the TXD input. When TXD remains in the dominant state (low) for longer than tDOM, the driver is switched to the recessive state, releasing the bus.The MAX14883E is available in a narrow, 8-pin SOIC package and operates over the -40°C to +125°C temperature range.ApplicationsBuilding AutomationHVACIndustrial ControlsSwitch Gear

The MAX14885E integrates high-bandwidth analog switches, level-translating buffers, and level-translating FET switches. The device implements a complete 2:2 dual-graphics crossover solution for VGA signal switching. The MAX14885E provides 12 very high-frequency 700MHz (typ) SPST switches for RGB signals, four low-frequency clamping switches for the display data channel (DDC) signals, two pairs of level-translating buffers for the HSYNC and VSYNC signals, and integrated extended ESD protection. The MAX14885E is used to select one of two sources to either of two destinations (seeTypical Operating Circuitin the full data sheet) within a laptop computer.Horizontal and vertical synchronization (SH_/SV_) inputs feature level-shifting buffers to support low-voltage controllers and standard 5V TTL-level monitors. DDC, consisting of SDA_ and SCL_, are FET switches that protect the low-voltage VGA source from potential damage from high-voltage presence on the monitor while reducing capacitive load.All 14 output terminals of the MAX14885E feature high-ESD protection to ±15kV Human Body Model (HBM) and ±6kV IEC 61000-4-2 Contact Discharge (see thePin Descriptionin the full data sheet). All other pins are protected to ±2kV HBM.The MAX14885E is specified over the extended -40°C to +85°C temperature range, and is available in a 40-pin TQFN (5mm x 5mm) package.ApplicationsNotebook Computer—Switchable Graphics
