FAQ
Q: What is the difference between CD4069UBE and 74HC04?
A: CD4069UBE operates from 3–18V (wider range) but is slower (50ns vs 7ns for 74HC04). 74HC04 is preferred for high-speed 5V logic; CD4069 is preferred for wide-voltage and analog applications.
Q: Can CD4069UBE be used as a linear amplifier?
A: Yes — the unbuffered (UB) version can be biased in its linear region with a feedback resistor (typically 10MΩ from output to input). This creates a high-gain inverting amplifier useful for crystal oscillators and audio circuits.
Q: Is CD4069 compatible with 3.3V ESP32 logic?
A: Yes. Power with 3.3V Vdd; VIH min = 2.31V, compatible with 3.3V logic outputs. Output will swing 0–3.3V, directly compatible with ESP32 GPIO.
