MAX3140規(guī)格書詳情
General Description
The MAX3140 is a complete universal asynchronous receiver-transmitter (UART) and a true fail-safe RS-485/RS-422 transceiver combined in a single 28-pin QSOP package for space-, cost-, and power-constrained applications. The MAX3140 saves additional board space as well as microcontroller (μC) I/O pins by featuring an SPI?/QSPI?/MICROWIRE?-compatible serial interface. It is pin-programmable for configuration in all RS-485/RS-422 networks.
