74F1071 18-Bit Undershoot/Overshoot Clamp and ESD Protection Device
General
The 74F1071 is an 18-bit undershoot/overshoot clamp which is designed to limit bus voltages and also to protect more sensitive devices from electrical overstress due to electrostatic discharge (ESD). The inputs of the device aggressively clamp voltage excursions nominally at 0.5V below and 7V above ground.
Features
s 18-bit array structure in 20-pin package s FASTВ® Bipolar voltage clamping action s Dual center pin grounds for min inductance s Robust design for ESD protection s Low input capacitance s Optimum voltage clamping for 5V CMOS/TTL applications

Note 1: Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied. Note 2: Voltage ratings may be exceeded if current ratings and junction temperature and power consumption ratings are not exceeded. Note 3: ESD Rating for Direct contact discharge using ESD Simulation Tester. Higher rating may be realized in the actual application.
