SN74HC573APWRE4 datasheet by Texas Instruments

SN74HC573APWRE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC573APWRE4?
  The maximum operating frequency of the SN74HC573APWRE4 is 50 MHz, but it can vary depending on the system design and capacitive load.
• 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 (POR) circuit to initialize the device.
• What is the recommended operating voltage range for the SN74HC573APWRE4?
  The recommended operating voltage range for the SN74HC573APWRE4 is 4.5V to 5.5V, but it can operate down to 3V with reduced performance.
• How do I handle the latch enable (LE) input during asynchronous inputs?
  During asynchronous inputs, it is recommended to keep the latch enable (LE) input low to prevent the output from changing unexpectedly. When the LE input is high, the output will follow the input, and when it is low, the output will be latched.
• What is the maximum capacitive load that the SN74HC573APWRE4 can drive?
  The maximum capacitive load that the SN74HC573APWRE4 can drive is 100 pF, but it can be increased with the use of an external buffer or repeater.
