uClamp0505A TM Clamp 5-Line ESD protection Array TM PROTECTION PRODUCTS - MicroClampPROTECTION PRODUCTS Features Description TM The Clamp series of TVS arrays are designed to pro- Transient protection for data lines to tect sensitive electronics from damage or latch-up due IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) to ESD. They are designed for use in applications where IEC 61000-4-4 (EFT) 40A (5/50ns) board space is at a premium. Each device requires less Protects five I/O lines 2 than 2.9mm of PCB area and will protect up to five lines.
