SN54LS673J datasheet by Texas Instruments

SN54LS673J Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS673J can operate at?
  The maximum clock frequency of the SN54LS673J is 30 MHz, but it can vary depending on the operating voltage and temperature.
• How do I ensure that the SN54LS673J is properly initialized during power-up?
  To ensure proper initialization, the CLR (Clear) input should be tied to VCC through a pull-up resistor, and the CLK (Clock) input should be held low during power-up. This ensures that the device is reset to a known state.
• What is the maximum capacitance that can be driven by the SN54LS673J outputs?
  The maximum capacitance that can be driven by the SN54LS673J outputs is 100 pF. Exceeding this value may cause signal degradation or oscillation.
• Can the SN54LS673J be used in a 3.3V system?
  No, the SN54LS673J is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may cause damage to the device or unpredictable behavior.
• How do I handle the asynchronous clear input (CLR) in my design?
  The asynchronous clear input (CLR) should be synchronized with the clock (CLK) signal to avoid metastability issues. This can be done using a flip-flop or a synchronizer circuit.
