HCPL-6430

Logic Output Optoisolators Overview

The HCPL-6430 is a commercial-grade, dual-channel high-speed optocoupler manufactured by Broadcom Limited. It features hermetic sealing in a 20-pin Leadless Ceramic Chip Carrier (LCCC) package and operates within a temperature range of -55°C to +125°C. The device integrates AlGaAs light-emitting diodes with high-gain photodetectors, supporting data rates up to 40 Mbps. Key electrical specifications include an isolation voltage of 1500 VDC and a common-mode transient immunity of 500 V/µs. It provides push-pull outputs compatible with TTL, STTL, LSTTL, and HCMOS logic families.
