The MAX1487ECPA is an integrated circuit (IC) component developed by Maxim Integrated. It is a rugged, low-power transceiver designed for RS-485 and RS-422 communication networks. With its versatile features, it serves as a reliable solution for various industrial applications requiring long-distance communication and noise immunity.
This IC is capable of operating over a wide voltage range, from +4.75V to +5.25V, making it compatible with various power supply systems. The MAX1487ECPA supports data rates up to 250kbps, providing a decent transfer speed for most industrial control systems. Moreover, it incorporates a fail-safe feature that ensures the receiver outputs logic-high levels when the inputs are open or shorted.
The MAX1487ECPA is designed to withstand harsh industrial environments, as it complies with the ESD (electrostatic discharge) protection standards of ±15kV (human body model) and ±15kV (IEC 61000-4-2, contact discharge). This robustness enhances its reliability and longevity in industrial applications that involve high-voltage fluctuations and electromagnetic interference.
Another prominent feature of this IC is its enhanced receiver input impedance, which allows up to 256 transceivers to be connected on a single bus. This feature not only simplifies the network design but also significantly reduces the cost of implementing large-scale RS-485 and RS-422 networks
