Product details

Description

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 QSOP package for space-, cost-, and power-constrained applications.

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 +5V supply and typically consumes only 645µA with the receiver active. Hardware-invoked shutdown reduces supply current to only 20µA. The UART and RS-485/RS-422 functions can be used together or indepen.
