The ST485EB is a low power transceiver for RS-485 and RS-422 communication, featuring a half-duplex interface and designed by STMicroelectronics. This device is tailored to meet the stringent requirements of industrial applications and is capable of operating in multi-point networks over long distances.

Key Features

• Low Quiescent Current: The ST485EB is optimized for low power consumption, drawing only 300 µA of supply current when unloaded or fully loaded with the drivers disabled.
• Wide Supply Voltage Range: It operates from a 5V supply, making it suitable for a variety of industrial applications.
• High Speed: Capable of transmitting data at speeds up to 5 Mbps, the ST485EB is well-suited for high-speed data communication in industrial networks.
• Thermal Shutdown Protection: The device includes thermal shutdown protection that disables the transmitter outputs when a temperature limit is exceeded, ensuring the transceiver's reliability and longevity.
• Failsafe Receiver: Even when the receiver inputs are left open, shorted, or connected to a terminated transmission line with no signal present, the receiver output maintains a high level.

Applications

The ST485EB is ideal for various applications that require robust and reliable data communication, such as:

• Industrial control systems
• Factory automation
• Building automation
• Networked security systems
• Remote data acquisition
