DM74LS244WM Frequently Asked Questions (FAQ)

  • The maximum operating frequency of the DM74LS244WM is 30 MHz, but it can vary depending on the load capacitance and the output current.

  • To ensure signal integrity, use a low-impedance output driver, minimize trace lengths, and use proper termination techniques to reduce reflections and ringing.

  • Yes, the DM74LS244WM can be used as a level translator, but ensure that the input voltage is within the recommended range (VCC-1.5V to VCC+0.5V) and that the output voltage is within the recommended range of the receiving device.

  • The power consumption of the DM74LS244WM depends on the operating frequency, input voltage, and output current. Typically, it ranges from 10-50 mW, but can be as high as 100 mW at maximum operating frequency.

  • To handle thermal issues, ensure good heat dissipation by using a heat sink, keeping the device away from other heat sources, and minimizing power consumption. The maximum junction temperature is 150°C.
