SNJ54LS163AJ datasheet by Texas Instruments

SNJ54LS163AJ Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SNJ54LS163AJ?
  The recommended operating voltage range for the SNJ54LS163AJ is 4.75V to 5.25V, with a typical voltage of 5V.
• How do I handle the asynchronous inputs on the SNJ54LS163AJ?
  The asynchronous inputs on the SNJ54LS163AJ, such as the clear (CLR) and clock (CLK) inputs, should be synchronized with the clock signal to ensure proper operation. This can be done using a flip-flop or a synchronizer circuit.
• What is the maximum clock frequency that the SNJ54LS163AJ can handle?
  The maximum clock frequency that the SNJ54LS163AJ can handle is 25 MHz, but this can vary depending on the operating voltage and temperature.
• How do I ensure data integrity when using the SNJ54LS163AJ in a noisy environment?
  To ensure data integrity in a noisy environment, it is recommended to use a decoupling capacitor between the power supply pins (VCC and GND) and to use a clock signal with a high slew rate to reduce the effects of noise on the clock input.
• Can I use the SNJ54LS163AJ in a 3.3V system?
  No, the SNJ54LS163AJ is not designed to operate at 3.3V and may not function correctly or may be damaged if operated at this voltage. It is recommended to use a voltage regulator or level shifter to convert the voltage to the recommended operating range.
