The ST485ERCDR is a robust low power transceiver module from the renowned semiconductor manufacturer STMicroelectronics. This device is designed to provide bidirectional data communications on multipoint bus transmission lines. It is part of the ST485 family and is specifically crafted for balanced data transmission at speeds of up to 5 Mbps.
Constructed to operate in harsh industrial environments, the ST485ERCDR is compliant with the RS-485 and RS-422 standards for differential data transmission. This makes it a perfect fit for applications that require high data integrity and reliability over long distances and in noisy environments.
One of the key features of the ST485ERCDR is its wide supply voltage range, from 4.75V to 5.25V, which allows for flexible integration into various system designs. Additionally, it boasts a very low quiescent current and includes a driver that is capable of handling up to 256 transceivers on the bus. This high fan-out capability is essential for complex network topologies.
The device also incorporates thermal shutdown protection and a fail-safe receiver that guarantees a high level of protection against line faults and excessive power dissipation. The thermal shutdown feature ensures that the device will protect itself and the system if the internal temperature exceeds safe operating limits.
For enhanced versatility, the ST485ERCDR comes in a compact SO-8 package, making it suitable for space-constrained applications. Its operating temperature range of -40°C to 85°C allows for deployment in a wide range of environmental conditions.
Whether it's for industrial control systems, networked security systems, building automation, or other data-intensive applications, the ST485ERCDR transceiver stands out with its reliability, robustness, and performance. It is a testament to STMicroelectronics' commitment to providing high-quality components for advanced electronic systems.
