MAX485CPA+ RS-485 Transceiver
Half-Duplex Architecture meets Low Power Design – The Professional Through-Hole PDIP-8 Transceiver Choice for Rugged Fieldbus Networks.
// High-Speed 2.5Mbps Differential Data Bus System Core Portfolio
The Industrial Fieldbus Connectivity Advantage
The MAX485CPA+ represents the ultimate industry-standard benchmark for high-performance serial communication networks demanding absolute noise immunity and multi-drop transceiver capabilities. Engineered by Maxim Integrated, this half-duplex RS-485/RS-422 transceiver features an advanced differential driver and receiver layout that minimizes EMI and reduces localized reflections. Operating seamlessly from a single +5V supply rail, it establishes deterministic data transit corridors across lengthy twisted-pair fieldbus systems inside a traditional 8-pin plastic DIP footprint.
- Single half-duplex bi-directional channel architecture optimizing line resource routing
- Advanced fail-safe receiver design securing known logic states under open circuits
- Through-hole wave solder leg anchors providing superior mechanical retention for field mainboards
Key Performance Advantages
2.5Mbps High Speed
Supports error-free serial data transfer rates up to 2.5 Mbps, fully fulfilling dynamic processing needs inside automated PLC backplanes.
Ultra-Low Active Current
Draws only 300 µA typical supply current, sharply decreasing structural power overhead and thermal dissipation markers across multi-node setups.
Through-Hole PDIP-8
Housed in a rugged dual-in-line plastic package, enabling effortless prototyping socket integration and absolute wave soldering connection durability.
