CD74AC20E Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for CD74AC20E is 2V to 6V, although it can operate up to 7V with reduced performance.
  • The output enable (OE) pin should be connected to GND to enable the outputs, and to VCC to disable the outputs. Leaving OE unconnected or floating can cause unpredictable behavior.
  • The maximum frequency of operation for CD74AC20E is typically around 100 MHz, but this can vary depending on the specific application, operating voltage, and load conditions.
  • Yes, CD74AC20E can be used in a 3.3V system, but the output voltage levels may not be fully compatible with 3.3V logic. It's recommended to use a level translator or voltage regulator to ensure proper operation.
  • To ensure proper power sequencing, it's recommended to power up the VCC pin before applying any input signals, and to power down the VCC pin after removing all input signals.
