SN54LS161AJ datasheet by Texas Instruments

SN54LS161AJ Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS161AJ can handle?
  The maximum clock frequency of the SN54LS161AJ is 36 MHz.
• How do I ensure that the SN54LS161AJ is properly reset during power-up?
  To ensure proper reset, connect the MR (Master Reset) pin to a 10kΩ pull-up resistor to VCC, and then to a capacitor to ground. This will ensure that the device is properly reset during power-up.
• What is the recommended operating voltage range for the SN54LS161AJ?
  The recommended operating voltage range for the SN54LS161AJ is 4.75V to 5.25V.
• How do I handle asynchronous inputs to the SN54LS161AJ?
  Asynchronous inputs should be synchronized with the clock signal using a flip-flop or a synchronizer circuit to prevent metastability issues.
• What is the maximum input voltage that the SN54LS161AJ can tolerate?
  The maximum input voltage that the SN54LS161AJ can tolerate is 7V, but it is recommended to keep the input voltage within the recommended operating voltage range of 4.75V to 5.25V.
