The MAX14842 translates digital signals between two domains that have different ground references of up to 72V. The device features six communication channels, two bidirectional and four unidirectional. Two of the four unidirectional channels go in each direction. The device is powered by two supply voltages that independently define the logic levels of each ground domain.The MAX14842 supports guaranteed data rates up to 30Mbps on the four unidirectional channels and up to 2Mbps on the two bidirectional channels. The bidirectional channels have open-drain outputs, making them suitable for I²C signals. I²C clock stretching and hot swapping is supported on the bidirectional channels.Undervoltage lockout ensures that the output pins have a defined behavior during power-up, power-down, and during supply transients. For proper operation, ensure that 0V ≤ (VGNDB - VGNDA) ≤ 72V. Note that GNDB must be greater than or equal to GNDA.The MAX14842 is available in a 16-pin TQFN package and is specified over the -40°C to +125°C automotive temperature range.ApplicationsBattery ManagementI2C, SMBus™, SPI™, and MICROWIRE™ SignalsMedical SystemsPower-Over-EthernetTelecommunication Systems
