BROADCOM ACPLM21L500E Digital Isolator

This is a low-power, high-speed digital CMOS optocoupler designed for industrial and electronic circuit isolation. Operating from 2.7V to 5.5V, it offers a typical speed of 5 Mbps, low input and supply current, and high common-mode rejection of at least 25 kV/µs at 1000V. Suitable for digital systems, microprocessor interfaces, ground loop elimination, and power control applications, it features a built-in Schmitt trigger, glitch-free operation at power-up, and reinforced insulation ratings up to 3750 VRMS. Compliant with UL, CSA, and IEC standards, it ensures safety, durability, and reliable high-speed data transfer in demanding environments.
