SN54LS163AJ datasheet by Texas Instruments

SN54LS163AJ Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS163AJ can operate at?
  The SN54LS163AJ can operate at a maximum clock frequency of 36 MHz.
• How do I ensure that the SN54LS163AJ is properly synchronized with the system clock?
  To ensure proper synchronization, the clock input (CLK) should be connected to a stable clock source, and the clock enable input (CE) should be tied to VCC or a logic high level.
• What is the maximum input voltage that the SN54LS163AJ can tolerate?
  The maximum input voltage that the SN54LS163AJ can tolerate is 5.5V. Exceeding this voltage may cause damage to the device.
• How do I handle the asynchronous clear (CLR) input?
  The asynchronous clear (CLR) input should be tied to VCC or a logic high level during normal operation. When CLR is low, the counter is reset to zero.
• What is the purpose of the ripple-blank (RB) output?
  The ripple-blank (RB) output is used to cascade multiple counters. When the counter overflows, the RB output goes low, indicating that the next counter in the cascade should be incremented.
