CD54HCT11F3A datasheet by Texas Instruments

CD54HCT11F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54HCT11F3A?
  The recommended operating voltage range for CD54HCT11F3A is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I handle the output enable (OE) pin in CD54HCT11F3A?
  The output enable (OE) pin should be connected to GND to enable the output, and to VCC to disable the output. Leaving it unconnected or floating can cause unpredictable behavior.
• What is the maximum clock frequency supported by CD54HCT11F3A?
  The maximum clock frequency supported by CD54HCT11F3A is 30 MHz, but it can operate up to 40 MHz with some degradation in performance.
• Can I use CD54HCT11F3A with 3.3V logic?
  While CD54HCT11F3A is designed for 5V operation, it can be used with 3.3V logic with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the device may not meet its specified timing parameters.
• How do I ensure proper power sequencing when using CD54HCT11F3A?
  To ensure proper power sequencing, apply power to VCC before applying any input signals, and ensure that VCC is stable before applying clock signals.
