MAX3140 SPI/MICROWIRE-Compatible UART

MAX3140 Description

19-1453; Rev 0; 6/99 SPI/MICROWIRE-Compatible UART with Integrated True Fail-Safe RS-485/RS-422 Transceivers General .
The MAX3140 is a complete universal asynchronous receiver-transmitter (UART) and a true fail-safe RS485/RS-422 transceiver combined in a single 28-pin.

MAX3140 Features

* an 8-word-deep receive FIFO that minimizes processor overhead and provides a flexible interrupt with four maskable sources, including address recognition on 9-bit networks. Two control lines are included for hardware handshaking
* one input and one output. The MAX3140 operates from a single +5

MAX3140 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. The MAX3140 includes a single RS-485/RS-422 driver and receiver featuring true
