ACML-7420-500E

Overview

The Broadcom ACML-7420-500E is a multi-channel, high-speed CMOS digital isolator featuring four independent channels. It utilizes magnetic coupling technology through thick insulation to provide electrical isolation between circuits. The device supports data rates up to 100 MBd and offers an insulation voltage of 5600 Vrms. It operates within a supply voltage range of 3 V to 5.5 V and maintains a common mode transient immunity of 25 kV/µs. The component is housed in a 16-SOIC package and functions reliably across an operating temperature range of -40°C to 125°C.
