SN74LS76AD datasheet by Texas Instruments

SN74LS76AD Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS76AD can handle?
  The maximum clock frequency of the SN74LS76AD is 25 MHz.
• How do I ensure that the SN74LS76AD is properly powered?
  The SN74LS76AD requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper power supply decoupling.
• What is the maximum input voltage that the SN74LS76AD can tolerate?
  The maximum input voltage that the SN74LS76AD can tolerate is 7V, but it's recommended to keep the input voltage within the recommended operating range of 4.5V to 5.5V to ensure reliable operation.
• How do I handle the asynchronous reset input (CLR) of the SN74LS76AD?
  The CLR input should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure that the flip-flop is not accidentally reset. When CLR is low, the flip-flop is reset, and when CLR is high, the flip-flop operates normally.
• What is the propagation delay of the SN74LS76AD?
  The typical propagation delay of the SN74LS76AD is 10 ns, but it can vary depending on the operating conditions and the specific application.
