Frequently Asked Questions
How can two NOR gates from CD74HC02M be configured to build a basic RS latch for a debounce circuit?
Cross-coupling the outputs of two 2-input NOR gates creates an SR latch where setting input S goes high to force Q high, and reset input R goes high to force Q low. With a 10 kΩ pull-up and a push-button switch driving each input, the latch resolves contact bounce within the first gate propagation delay of approximately 7 ns at 5 V, producing a clean digital edge within 10 ns of the initial button press.
What is the maximum output sink current of the CD74HC02M, and does it allow direct LED drive?
Each gate can sink up to 5.2 mA at a VOL below 0.33 V at 4.5 V supply. This is sufficient to drive a 3 mA indicator LED through a 430 Ω series resistor directly from the NOR gate output, eliminating a transistor driver for single-LED status indicators in a low-cost control panel design.
Over what supply voltage range does the CD74HC02M operate, and how does that affect 3.3 V microcontroller interfacing?
The device operates from 2 V to 6 V. At 3.3 V supply the input high threshold is approximately 2.31 V, compatible with standard 3.3 V GPIO outputs from STM32 or nRF52 microcontrollers. No level translator is required when the MCU and CD74HC02M share the same 3.3 V rail, and propagation delay at 3.3 V is typically below 13 ns at a 50 pF load.
For a compact design replacing four discrete NOR functions, how does packing all 4 gates into the CD74HC02M's SOIC-14 save board space?
A single CD74HC02M SOIC-14 occupies about 35 mm² including courtyard, compared to four individual SOT-23-5 single-gate packages that together require roughly 60 mm². Consolidating glue logic into one SOIC-14 also reduces solder joint count from 20 to 14, lowering reflow defect risk and simplifying board inspection during automated optical inspection at production volumes above 10,000 units.
