SN54LS160AJ datasheet by Texas Instruments

SN54LS160AJ Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS160AJ can operate at?
  The maximum clock frequency of the SN54LS160AJ is 36 MHz, but it can vary depending on the operating voltage and temperature.
• How do I ensure that the SN54LS160AJ 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 add a 0.1μF capacitor between the MR pin and GND to filter out any noise.
• What is the recommended operating voltage range for the SN54LS160AJ?
  The recommended operating voltage range for the SN54LS160AJ is 4.75V to 5.25V, but it can operate from 4.5V to 5.5V with reduced performance.
• How do I handle the asynchronous reset signal (MR) during normal operation?
  During normal operation, the MR pin should be tied to VCC through a 10kΩ pull-up resistor to prevent accidental resets. If a reset is required, pull the MR pin low for at least 10ns.
• What is the maximum input voltage that the SN54LS160AJ can tolerate on its input pins?
  The maximum input voltage that the SN54LS160AJ can tolerate on its input pins is 5.5V, but it's recommended to keep the input voltage within the operating voltage range (4.75V to 5.25V) for reliable operation.
