Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the specified range of 4.75 V to 5.25 V.
    • Connect the ground (GND) pin to a stable reference potential.
  2. Input Signals:

    • Input voltages should be within the valid range: 0 V to 0.8 V for low level (VIL) and 2.0 V to 5.5 V for high level (VIH).
    • Be aware of the input current limits: -20 μA for high level and -1.0 mA for low level.
  3. Output Signals:

    • The output voltage levels should be within the specified ranges: 2.4 V to 5.0 V for high level (VOH) and 0 V to 0.5 V for low level (VOL).
    • The output can source up to -0.4 mA and sink up to 16 mA.
  4. Propagation Delay:

    • The propagation delay time (tpd) is typically 12 ns at room temperature (25°C) and with a supply voltage of 5 V.
  5. Power Dissipation:

    • The maximum power dissipation (PD) should not exceed 350 mW to avoid overheating and potential damage to the device.
  6. Handling and Storage:

    • Handle the SN74F244N with care to avoid static discharge, which can damage the device.
    • Store in a dry, cool environment to prevent moisture damage.
  7. Mounting:

    • Ensure proper soldering techniques are used to avoid thermal shock and mechanical stress on the pins.
    • Use a heat sink if necessary to manage power dissipation, especially in high-power applications.
