FAQ
Q: How many OR gates are in one SN74HC32N?
A: Four independent 2-input OR gates. Each gate has two inputs (A, B) and one output (Y = A OR B).
Q: Is SN74HC32N compatible with 3.3V Arduino or ESP32?
A: Yes. The 74HC family operates from 2V to 6V, making it fully compatible with 3.3V logic systems.
Q: What is the difference between 74HC32 and 74HCT32?
A: The 74HCT32 has TTL-compatible input thresholds (VIH = 2.0V), while 74HC32 uses CMOS thresholds. Use 74HCT32 when interfacing with 5V TTL outputs.
