Maxim Integrated MAX3110ECWI+G36 Line Transceiver, 28-Pin SOIC

The MAX3110E/MAX3111E combine a full-featured universal asynchronous receiver/transmitter (UART) with ±15kV ESD-protected RS-232 transceivers and integrated charge-pump capacitors into a single 28-pin package for use in space-, cost-, and power-constrained applications. The MAX3110E/MAX3111E also feature an SPI™/QSPI™/MICROWIRE™-compatible serial interface to save additional board space and microcontroller (μC) I/O pins. A proprietary low-dropout output stage enables the 2-driver/2-receiver interface to deliver true RS-232 performance down to VCC = +3V (+4.5V for MAX3110E) while consuming only 600μA. The receivers remain active in a hardware/software-invoked shutdown, allowing external devices to be monitored while consuming only 10μA. Each device is guaranteed to operate at up to 230kbps while maintaining true EIA/TIA-232 output voltage levels.
