MAX3072EESA+T RS-485/RS-422 Transceiver IC Chip
The MAX3072EESA+T is a high-performance, 3.3V RS-485/RS-422 transceiver from Maxim Integrated (now part of Analog Devices), featuring robust ±15kV ESD protection, fail-safe operation, and hot-swap capability. This half-duplex transceiver integrates one driver and one receiver in a compact 8-pin SOIC package, making it ideal for industrial communication networks and data transmission systems. Designed for reliable operation in harsh environments, the device supports data rates up to 250kbps and operates over a wide temperature range of -40°C to +85°C. Its advanced protection features and low power consumption make it suitable for applications requiring long-distance, noise-immune communication with minimal power dissipation.
MAX3072EESA+T Key Specifications
The MAX3072EESA+T delivers exceptional performance with its true fail-safe receiver design that guarantees a logic-high output when inputs are open or shorted, maintaining EIA/TIA-485 compatibility. The device features hot-swap input structure on DE and RE pins to eliminate false transitions during power-up or hot insertion, while its enhanced slew-rate limiting minimizes EMI and reduces reflections for error-free data transmission. Key specifications include a supply voltage range of 3V to 3.6V, typical supply current of 800µA, receiver hysteresis of 100mV, and 1/8-unit load receiver input impedance allowing up to 256 transceivers on the bus. The device also offers low-power shutdown mode with typical current draw of only 50nA, comprehensive fault protection including thermal shutdown, and excellent ESD protection meeting ±15kV human body model standards.
