Frequently Asked Questions
How many channels does the ISO7721BDW support?
The ISO7721BDW features 2 channels of digital isolation, allowing it to isolate two independent digital signal lines simultaneously. This dual-channel capability is ideal for SPI interfaces, bidirectional control signals, and other multi-line communication protocols that require galvanic separation between system domains.
What package is used for the ISO7721BDW?
The ISO7721BDW is housed in a 16-pin Small Outline Package (SOP16, .4-inch body width), with JESD-30 code R-PDSO-G16. This surface-mount package provides adequate creepage and clearance for digital isolation applications while maintaining a compact PCB footprint suitable for industrial and communications designs.
Is the ISO7721BDW RoHS compliant?
Yes, the ISO7721BDW carries a Pb-free code of Yes and a JESD-609 code of e4, confirming full RoHS compliance with lead-free and halogen-free material requirements. Its plastic/epoxy package body meets global environmental regulations for use in consumer, industrial, and medical end products.
What are typical applications for the ISO7721BDW?
The ISO7721BDW is widely used in industrial automation for isolating field-side signals from controller logic, in RS-485 and SPI bus isolation, motor drive gate driver interfaces, and isolated power supply feedback paths. It suits any design where two voltage domains must communicate without a direct electrical connection for safety or noise reduction.
