Frequently Asked Questions
How many NOR gate functions does the CD74HC02EE4 contain and what are the input configurations?
The CD74HC02EE4 contains 4 independent NOR gate functions, each with 2 inputs, for a total of 8 input pins plus 4 output pins in a 14-pin DIP package. All 4 gates operate simultaneously from a single 2 V to 5.5 V power supply.
What output sink current can the CD74HC02EE4 deliver and what load capacitance does it support?
The CD74HC02EE4 provides a maximum output sink current (I_OL) of 5.2 mA per gate output, rated into a 50 pF load capacitance. This current capability is sufficient to directly drive standard CMOS inputs and LEDs through current-limiting resistors without additional buffers.
When would a designer choose CD74HC02EE4 over a surface mount equivalent for a new NOR gate application?
The CD74HC02EE4 uses a 14-pin DIP package, making it the preferred choice for breadboard prototyping, through-hole PCB assemblies, and educational lab kits where hand soldering or socket insertion is required. For production SMT boards, the SOIC-14 or TSSOP-14 variants of the CD74HC02 would be chosen instead to reduce board space by up to 60%.
