摘要:
An ESD protection circuit for dual 3V/5V supply devices. ESD protection circuit 10 comprises a switching element 12 connected between a bond pad 14 and primary protection device 16. Primary protection device 16 comprises MOS circuitry designed for 3V operation that suffers from oxide reliability problems when 5V signals are applied directly. Switching element 12 separates the primary protection device 16 from 5V signals which may appear at bond pad 14.
