74HC244DB,112 Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the 74HC244DB,112 is 40 MHz, but it can vary depending on the output load and supply voltage.
  • To ensure proper power supply, connect VCC to a stable 2V to 6V power source, and GND to a solid ground plane. Also, decouple the power supply with a 0.1uF capacitor to reduce noise.
  • The 74HC244DB,112 can sink or source up to 25mA per output pin, but the total current should not exceed 100mA for the entire device.
  • The enable inputs (OE1 and OE2) are active-low, so connect them to GND to enable the outputs. Connect them to VCC to disable the outputs. Use a pull-up or pull-down resistor if the enable inputs are not driven.
  • The propagation delay of the 74HC244DB,112 is typically around 10ns to 20ns, depending on the supply voltage and output load.
