74HC4002D,653

Overview

The Nexperia 74HC4002D,653 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 utilizes a 14-lead plastic small outline package (SO14) with a body width of 3.9 mm, conforming to the SOT108-1 outline. Static characteristics include high-level input voltages up to 4.2 V at 6.0 V supply and low-level output voltages as low as 0.26 V under specific load conditions.

Feature Summary

• Dual 4-input NOR logic function
• CMOS low power dissipation
• High noise immunity
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Applications

• General digital logic processing
