The MAX490ESA+T is a low-power, high-speed, quad-channel, single-supply RS-485/RS-422 transceiver designed for bidirectional data communication over long cable lengths. It is commonly used in industrial and automotive applications where noise immunity and robust performance are critical.
Key features of the MAX490ESA+T include:
1. Quad-Channel Transceiver: The component consists of four independent transceivers, allowing simultaneous bidirectional communication on up to four RS-485 or RS-422 buses.
2. Robust Communication: With high input impedance (30 kΩ) and differential outputs, the MAX490ESA+T provides excellent common-mode rejection capability, minimizing the impact of noise and interference.
3. Wide Supply Voltage Range: The component operates with a single supply voltage ranging from +4.5V to +5.5V, making it compatible with a variety of power sources.
4. High Data Rate: The MAX490ESA+T supports data rates up to 25Mbps, allowing fast and efficient data transmission.
5. Low Power Consumption: The IC is designed for low power operation, consuming only 200µA of quiescent supply current, saving energy and prolonging battery life in portable devices.
6. ESD Protection: The transceiver provides ±15kV electrostatic discharge (ESD) protection on the RS-485/RS-422 bus pins, safeguarding against potential damage from static discharges
