The MAX3485ESA+ is an integrated circuit (IC) component designed by Maxim Integrated. It belongs to the MAX3485 family, which is a line of low-power, half-duplex RS-485/RS-422 transceivers. This IC is widely used in industrial automation, process control systems, HVAC systems, and other applications requiring reliable long-distance serial communication.
One of the key features of the MAX3485ESA+ is its ability to operate over a wide voltage range, from 3V to 5.5V, making it suitable for low-power applications. Additionally, it has a low shutdown current of just 10nA, contributing to its energy efficiency.
The IC supports a maximum data rate of 250kbps with a slew-limited driver output, enabling robust long-distance communication. It utilizes a half-duplex configuration, meaning it allows communication in only one direction at a time, which is ideal for multi-point networks.
The IC features a fail-safe receiver input, ensuring a high level of noise immunity. It also includes a receiver output enable pin that can be used to disable the receiver input, providing further control over the communication process. Additionally, the MAX3485ESA+ incorporates thermal shutdown protection, preventing damage due to excessive temperatures
