The MAX3087EPA+ is a small and versatile interface driver, receiver, and transceiver. It is capable of driving high-speed, high-impedance transceiver lines with high bandwidth and low power consumption. It is compatible with both 3.3V and 5V logic systems and is designed for RS-485 and RS-422 applications.

The MAX3087EPA+ integrates a full duplex RS-485 transceiver, a full receiver and a single-ended driver. It is capable of operating from -40°C to +85°C temperature range, and is cost-effective for harsh environment applications. The MAX3087EPA+ also offers low power consumption and meets the industry standard EMI and surge protection requirements.

Application Field

The MAX3087EPA+ is designed for communication systems, computers, PLCs, motion control, military and industrial automation systems. Its low power, wide temperature range and industry standard EMI protection makes it suitable for hazardous location applications. It is also compatible with many kinds of protocols, such as RS-232, RS-485, RS-422, I2C and SPI.

The MAX3087EPA+ is capable of providing reliable and secure data transfer over long distances. Its features, such as low power dissipation, low voltage level detection thresholds, high-speed data rates, and low EMI immunity, make it suitable for applications in noisy environments.

The MAX3087EPA+ is also well suited for applications that have high levels of physical layer isolation, such as Ethernet, Fibre Channel, and Serial ATA, as well as for point-to-point digital communication links.

Working Principle

The MAX3087EPA+ operates on the half-duplex mode in which only one device can transmit data at a time. It uses a differential pair of bus input pins to receive data from other devices, and a single-ended driver to transmit data. The device is capable of running up to 4 Mbps and contains two integrated drivers, receivers and transceivers.

The MAX3087EPA+ is capable of automatically detecting the logic level of the received data and adjusting the output level accordingly. It also features adjustable data-rate selection between the RS-485 and RS-422 protocols. Additionally, it incorporates full-duplex E-channel autoresponse, which enables compatibility with switches and hubs for network connection.

It also has a hardware power-down function that shuts down the device when there is no data activity on the lines, thus providing additional power savings. The device also includes a built-in noise filter which helps reject noise and other signal interference. The MAX3087EPA+ also features a fault-tolerant architecture which increases reliability and robustness.

The MAX3087EPA+ is a versatile, low power, and cost-effective interface driver, receiver and transceiver. Its features, such as wide temperature range and EMI protection, make it suitable for harsh environment applications. Its low power, wide bandwidth, and fault-tolerant architecture make it suitable for digital communication links, industrial automation systems and Ethernet networks. The MAX3087EPA+ also offers full-duplex communication and adjustable data rates between RS-485 and RS-422.
