GENERAL DESCRIPTION
Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. An integrated LDO provides a simple and space-efficient architecture for providing power to the cable-side of the IC. The MAX14853/MAX14855 include one drive channel and one receive channel. The receiver is ¼-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 and receiver inputs are protected from ±35kV electrostatic discharge (ESD) to GNDB on the cable-side, as specified by the Human Body Model (HBM). The MAX14853/MAX14855 are available in a wide body 16-pin SOIC package and operate over the -40°C to +105°C temperature range. APPLICATIONS
