Advanced Clamp Diode for 3.3V PCI System Integrity

DESCRIPTION

The clamp diode is essential for ensuring data integrity in 3.3V PCI systems, as specified in PCI standard 4.2.2.2. It effectively protects 3.3V devices interfacing with 5V PCI systems, managing voltage overshoot up to 11V. Designed for high-speed applications, it supports zero wait-state and boasts the fastest speed grades of -1 and -09, simplifying implementation while ensuring high integration levels. The device is compliant with 5V PCI timing for up to 8 loads, making it a reliable choice for leading companies in reconfigurable computing.
