Description

The MAX488CSA+T is a low-power, half-duplex RS-485/RS-422 transceiver designed for communication in harsh electrical environments. It is part of Maxim Integrated’s MAX485 family and is suitable for digital communication applications where high-speed data transfer is required. This device offers a slew-rate limited driver that reduces EMI and reflections caused by improperly terminated cables, making it ideal for short-haul applications.
Key features include operation from a single 5V supply, low current consumption (300 µA in active mode and 1 µA in shutdown), and a wide common-mode voltage range. It supports data rates up to 250 kbps, making it suitable for moderate-speed applications. The MAX488CSA+T is capable of driving up to 32 transceivers on the bus, enhancing its suitability for networked systems. It also provides thermal shutdown protection and maintains fail-safe receiver inputs to prevent false data triggering.
The device is encapsulated in compact packages and is typically used in industrial control, building automation, and other systems requiring robust and reliable communication links.
