MC74HC244ADWR2G Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the MC74HC244ADWR2G is 40 MHz.
  • To ensure signal integrity, use a low-impedance output driver, minimize trace lengths, and use a ground plane to reduce noise and electromagnetic interference (EMI).
  • The recommended power-on sequence is to apply VCC before applying any input signals, and to ensure that all inputs are at a valid logic level before applying VCC.
  • Use a heat sink or thermal pad to dissipate heat, and ensure good airflow around the device. The maximum junction temperature is 150°C.
  • The MC74HC244ADWR2G has human body model (HBM) ESD protection of ±2 kV and charged device model (CDM) ESD protection of ±1 kV.
