MAX14840PMB1

MAX14840PMB1 Peripheral Module

Description

The MAX14840PMB1 peripheral module provides the necessary hardware to interface the MAX14840E RS-485 transceiver to any system that utilizes PmodTM-compatible expansion ports configurable for a UART interface. The IC is a +3.3V ESD-protected transceiver intended for half-duplex RS-485 communication up to 40Mbps*. These transceivers are optimized for high speeds over extended cable runs, while maximizing tolerance to noise.
The IC features symmetrical fail-safe and larger receiver hysteresis, providing improved noise rejection and improved recovered signals in high-speed and longcable applications.
*The maximum communication speed of this module is generally less than 10Mbps due to the presence of current-limiting resistors on the data lines of this module and possibly also the host board.

Refer to the MAX14840E IC data sheet for detailed information regarding operation of the IC.
