SN74LS73ADR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS73ADR is 35 MHz.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to a logic high during power-up. This will set the flip-flops to a known state.
  • The recommended operating voltage range for the SN74LS73ADR is 4.75V to 5.25V.
  • No, the SN74LS73ADR is not designed to operate at 3.3V. It is a 5V device and should only be used in 5V systems.
  • The asynchronous reset (CLR) input should be tied to a logic high during normal operation. When CLR is low, the flip-flops are reset to a logic low state.
