SN74AC574PWR datasheet by Texas Instruments

SN74AC574PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74AC574PWR can handle?
  The maximum clock frequency of the SN74AC574PWR is 100 MHz.
• How do I ensure that the flip-flops are properly initialized during power-up?
  To ensure proper initialization, connect the preset (PRE) input to VCC and the clear (CLR) input to GND during power-up. This sets the outputs to a known state.
• What is the purpose of the output enable (OE) input?
  The output enable (OE) input is used to enable or disable the outputs. When OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state.
• Can I use the SN74AC574PWR in a 3.3V system?
  Yes, the SN74AC574PWR is compatible with 3.3V systems. However, ensure that the input signals are within the recommended voltage range (VCC - 0.5V to VCC + 0.5V) to maintain proper operation.
• How do I handle asynchronous inputs to the flip-flops?
  To handle asynchronous inputs, use synchronous inputs or add external synchronization circuits to ensure that the inputs are synchronized with the clock signal.
