SN74AC374DWRE4 datasheet by Texas Instruments

SN74AC374DWRE4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that this device can handle?
  The maximum clock frequency of the SN74AC374DWRE4 is 100 MHz, but this can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the flip-flops are properly initialized on power-up?
  To ensure proper initialization, connect the Master Reset (MR) input to a pull-up resistor and a capacitor to VCC. This will ensure that the flip-flops are reset on power-up and then release the reset when the capacitor is fully charged.
• What is the recommended termination scheme for the outputs of this device?
  The recommended termination scheme for the outputs of the SN74AC374DWRE4 is to use a 33-ohm series resistor and a 47-pF capacitor to VCC or GND, depending on the output loading and signal integrity requirements.
• Can I use this device in a 3.3V system, and if so, what are the limitations?
  Yes, the SN74AC374DWRE4 can be used in a 3.3V system, but the input voltage thresholds and output voltage levels will be different from those specified in the datasheet. Consult the datasheet for specific details on 3.3V operation.
• How do I handle the asynchronous reset input (MR) in a synchronous design?
  In a synchronous design, the asynchronous reset input (MR) should be synchronized with the clock signal using a flip-flop or a synchronizer circuit to avoid metastability issues.
