SN74LS73AN Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS73AN is 35 MHz.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to a logic high level during power-up. This will set the flip-flops to a known state.
  • The recommended operating voltage range for the SN74LS73AN is 4.75V to 5.25V.
  • No, the SN74LS73AN is not designed to operate at 3.3V. It is a 5V device and should only be used in 5V systems.
  • During normal operation, the CLR input should be tied to a logic high level to prevent accidental resets. If a reset is needed, the CLR input can be momentarily pulled low.
