ADM487EARZ Description

Short technical summary and product information.

The ADM487EARZ is a 5V low-power half-duplex RS-485/RS-422 transceiver from Analog Devices. It integrates one driver and one receiver, supporting data rates up to 250 kbps. The device features ±15 kV ESD protection (HBM) on the RS-485 I/O pins, ensuring robust operation in harsh environments. With a common-mode input range of -7V to +12V and receiver hysteresis of 70 mV, it provides reliable communication over long bus lengths. The transceiver includes thermal shutdown and short-circuit protection for enhanced safety. The ADM487EARZ can support up to 128 nodes on a bus due to its 1/4 unit load receiver input impedance. It is available in an 8-pin SOIC surface-mount package, operating over a temperature range of -40°C to +85°C (datasheet and DB; manufacturer page lists -25°C to +85°C). The reduced slew rate limits EMI, making it suitable for industrial control, energy metering, and lighting systems.
