Broadcom

Broadcom carries the optocoupler lineage from HP, Agilent and Avago, and the profiles here cover the two jobs that line is bought for. The first is high-speed digital isolation: 10 MBd logic-gate optocouplers such as the 6N137 in DIP-8 and the HCPL-0600 in surface-mount SO-8, carrying fieldbus, encoder and data links across a galvanic barrier without giving up edge speed. The second is isolated power-stage driving: the HCPL-316J smart gate-drive optocoupler integrates desaturation detection and fault feedback around a 2.5 A-peak output stage, so protection logic that once took a board of discretes sits inside one SO-16 device. Read the whole ordering string when you qualify a code: the suffix carries the substance — packing form and lead-free options such as -500E — and the isolation and common-mode figures belong to the exact variant, not the family name. Match the full code, package and packing in your RFQ.

Sourcing notes for Broadcom parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
