The MAX487ECPA is an integrated circuit (IC) component that belongs to the family of MAX481, MAX483, MAX485, MAX487, MAX489 RS-485/RS-422 transceivers. This IC is designed to facilitate robust half-duplex communication over long distances using twisted-pair or shielded cables. It is widely used in industrial automation, instrumentation, and communication systems.
One of the key features of the MAX487ECPA is its ability to operate over a wide supply voltage range, from 4.5V to 5.5V, making it compatible with various power sources commonly used in industry. Additionally, this IC is capable of withstanding high levels of electromagnetic interference (EMI) due to its integrated ESD protection, making it suitable for demanding industrial environments.
The MAX487ECPA supports data rates of up to 2.5Mbps, allowing for fast and efficient transmission of data. It features a low quiescent current in shutdown mode, which helps to conserve power when the device is not actively transmitting or receiving data. The shutdown feature is particularly useful when designing battery-powered applications or devices with power-saving requirements.
To ensure reliable communication, the MAX487ECPA implements slew-rate-limited driver outputs to minimize reflections and reduce noise. It employs a true fail-safe receiver, ensuring a high impedance output when the device is not powered or during a ground fault condition
