Fairchild 74F1071 Data Handbook
Summary
The 74F1071 is a specialized 18-bit Undershoot/Overshoot Clamp integrated circuit designed to safeguard digital systems from electrical overstress and voltage anomalies. It provides continuous, fast bipolar voltage clamping action and robust ESD protection rated up to ±10 kV, making it ideal for reliability in 5V CMOS/TTL environments. This manual serves as a comprehensive technical guide, detailing the device's operational theory, absolute maximum ratings, precise DC electrical characteristics, and available package options (SOIC, SSOP, TSSOP) for circuit designers requiring reliable bus voltage protection.
