HEF4072BP,652

Inverter Gates Overview

The HEF4072BP,652 is a dual 4-input OR gate integrated circuit manufactured by NXP. It operates within a supply voltage range of 3 V to 15 V and features fully buffered outputs for high noise immunity. The device utilizes a 14-lead plastic DIP package (SOT27-1). Propagation delays vary with voltage: at 5 V, delays are up to 155 ns; at 10 V, up to 70 ns; and at 15 V, up to 55 ns. Output transition times follow similar voltage-dependent profiles.

Inverter Gates Feature Summary

• Provides positive dual 4-input OR logic function
• Fully buffered outputs ensure highest noise immunity
• Maintains pattern insensitivity of output impedance

Inverter Gates Applications

• Digital logic circuits requiring OR functionality
• Signal processing systems
• Industrial control applications

Inverter Gates Procurement Notes

Verify the component matches the HEF4072B specification sheet from Philips/NXP dated January 1995. Confirm the package type is 14-lead DIL plastic (SOT27-1) and that the manufacturer designation aligns with NXP USA Inc. Ensure the part number suffix 652 corresponds to the correct tape and reel or tube packaging as specified in official ordering information.

Inverter Gates Selection Notes

Select this component when a dual 4-input OR gate is required within the HE4000B logic family. Consider the propagation delay characteristics relative to the operating voltage. Verify compatibility with the system's load capacitance requirements, as delays increase with higher CL values according to the provided formulas.

Inverter Gates Part Context

This component belongs to the HE4000B logic family, which includes various standard logic functions. The HEF4072B specifically implements the OR gate function. It is part of NXP's comprehensive portfolio of expertly engineered solutions designed for robust performance in digital electronics.

Inverter Gates Replacement Considerations

Check for direct substitutes within the HE4000B series such as the HEF4071 (dual 2-input OR gate) if fewer inputs are needed. Ensure any replacement maintains the 14-lead DIP package and compatible voltage ranges.
