74HC4002DB,112

Overview

The Nexperia 74HC4002DB,112 is a dual 4-input NOR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS input levels and complies with JEDEC standards JESD8C and JESD7A. It includes clamp diodes on inputs for interfacing with voltages exceeding VCC. Static characteristics specify high-level output voltage up to 5.9 V at 2.0 V supply and low-level output voltage down to 0.1 V at 2.0 V supply. Dynamic performance includes propagation delays ranging from 17 ns to 150 ns depending on voltage and temperature.

Feature Summary

• Dual 4-input NOR logic function
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Input clamp diodes enable current limiting resistor usage

Applications

• General digital logic processing
• Signal gating and control circuits
• Industrial temperature environment applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and availability status. Confirm that the component meets required environmental specifications such as RoHS compliance before integration into final designs. Check for any recent product change notices or end-of-life announcements directly from Nexperia to ensure long-term supply stability.

Selection Notes

Select this component when a dual 4-input NOR gate is required in a surface-mount SSOP-14 package. Ensure the design voltage stays within the 2.0 V to 6.0 V range for optimal performance. Consider the specified operating temperature range of -40 °C to +125 °C for harsh environments. Verify pin compatibility if replacing legacy parts, noting that previous SSOP variants may have been discontinued.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by Nexperia. The 74HC4002 specifically provides two independent 4-input NOR gates in a single package. It is designed for general-purpose digital applications requiring reliable logic operations with low power consumption and high noise immunity across a wide voltage range.

Replacement Considerations

The datasheet revision history indicates that the type number 74HC4002DB (SSOP14) was removed in version 6. Customers should verify current availability and potential alternative packages like SO14 or TSSOP14 through official Nexperia channels.
