SN74HC573APWR datasheet by Texas Instruments

SN74HC573APWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC573APWR can handle?
  The maximum clock frequency of the SN74HC573APWR is 35 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the output is not corrupted during power-up or power-down?
  To ensure that the output is not corrupted during power-up or power-down, it is recommended to use an external pull-up or pull-down resistor on the output pins, and to use a power-on reset circuit to initialize the device.
• Can I use the SN74HC573APWR in a 5V system?
  Yes, the SN74HC573APWR is compatible with 5V systems, but it is recommended to use a voltage regulator to ensure a stable 5V supply, and to follow proper PCB design and layout guidelines to minimize noise and interference.
• How do I handle the latch enable (LE) input?
  The latch enable (LE) input should be tied to a logic high (VCC) to enable the latch function, or to a logic low (GND) to disable the latch function. It is recommended to use a pull-up or pull-down resistor to ensure a stable logic level.
• What is the maximum current that the SN74HC573APWR can sink or source?
  The maximum current that the SN74HC573APWR can sink or source is 25 mA per output pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
