MM74HC273WMX Frequently Asked Questions (FAQs)

  • The MM74HC273WMX can handle clock frequencies up to 35 MHz.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC or GND as required, and ensure that the clock (CLK) input is stable during power-up.
  • The recommended operating voltage range for the MM74HC273WMX is 2.0 V to 6.0 V.
  • Yes, the MM74HC273WMX is compatible with 3.3 V systems, but ensure that the input signals are within the recommended voltage range.
  • Asynchronous inputs should be synchronized with the clock signal using a synchronizer circuit or a flip-flop with a synchronous reset to prevent metastability issues.
