Product Details

The MAX14840PMB1 peripheral module provides the necessary hardware to interface the MAX14840E RS-485 transceiver to any system that utilizes Pmod™-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 long-cable applications.
Refer to the MAX14840E IC data sheet for detailed information regarding operation of the IC.
