HCPL-9030-300

Overview

The HCPL-9030-300 is a high-speed digital isolator from Broadcom Limited, utilizing magnetic coupling technology to provide electrical isolation between circuits. It features two independent channels with unidirectional signal transmission capability. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. Key electrical specifications include an insulation voltage of 2500 Vrms, a propagation delay of 15 ns, and a common-mode transient immunity of 15 kV/µs. It is housed in an 8-pin DIP Gull Wing package suitable for surface mount installation.
