Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the specified range of 2.0V to 6.0V.
    • Connect the ground (GND) pin to a stable 0V reference.
  2. Input Signals:

    • Apply input signals (D, D?) that meet the input voltage levels: VIL ≤ 0.8V and VIH ≥ 3.5V when VCC = 5V.
    • Use appropriate pull-up or pull-down resistors if necessary to ensure clean logic levels.
  3. Output Signals:

    • The output pins (Q, Q?) will provide valid logic levels: VOL ≤ 0.4V and VOH ≥ 4.5V when VCC = 5V.
    • Ensure the load connected to the output does not exceed the maximum current ratings (IOL = 25mA, IOH = -25mA).
  4. Timing Considerations:

    • Account for the propagation delay time (tp) of 11 to 22 nanoseconds when designing timing-sensitive circuits.
    • Use decoupling capacitors close to the power pins to minimize noise and improve stability.
  5. Environmental Conditions:

    • Operate the device within the commercial temperature range of 0°C to 70°C.
    • Store the device in an environment with temperatures between -65°C and 150°C.
  6. Handling:

    • Handle the device with care to avoid damage from electrostatic discharge (ESD).
    • Follow proper soldering techniques to ensure reliable connections and prevent thermal damage.
  7. Testing:

    • Verify the functionality of the device using a known good test circuit before integrating it into your design.
    • Use an oscilloscope to monitor signal integrity and timing characteristics during testing.
