CD54HCT86F3A datasheet by Texas Instruments

CD54HCT86F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54HCT86F3A?
  The recommended operating voltage range for CD54HCT86F3A is 4.5V to 5.5V, although it can operate down to 3.5V with reduced performance.
• How do I handle the output enable (OE) pin in CD54HCT86F3A?
  The output enable (OE) pin should be connected to GND to enable the outputs. If left floating, the outputs will be in a high-impedance state. It's recommended to tie OE to GND or VCC through a pull-down resistor to ensure proper operation.
• What is the maximum clock frequency supported by CD54HCT86F3A?
  The maximum clock frequency supported by CD54HCT86F3A is 30 MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
• How do I ensure proper power sequencing when using CD54HCT86F3A?
  To ensure proper power sequencing, apply power to VCC before applying any input signals. Also, ensure that the input signals are stable before applying the clock signal.
• What is the recommended termination scheme for CD54HCT86F3A outputs?
  The recommended termination scheme for CD54HCT86F3A outputs is to use a 10kΩ to 20kΩ pull-up resistor to VCC, depending on the specific application and load requirements.
