AD260BND-3

Overview

The AD260BND-3 is a five-channel digital isolator from the IsoLogic series, manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide robust signal isolation with an insulation voltage of 3500 Vrms and a common-mode transient immunity of 10 kV/µs. The device operates at data rates up to 20 MHz and supports unidirectional logic transmission. Designed for through-hole mounting in a 22-pin PDIP package, it functions on a single 5 V supply with a typical operating current of 4 mA. The component covers an industrial temperature range from -25°C to +85°C.
