Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 4.75V to 5.25V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Apply input signals such that the high level (V_IH) is at least 3.15V and the low level (V_IL) is no more than 0.8V.
   • Avoid exceeding the maximum input voltage of 5.25V to prevent damage to the device.

3. Output Signals:

   • The output high level (V_OH) should be at least 2.4V when sourcing 0.4mA.
   • The output low level (V_OL) should be no more than 0.5V when sinking 4.0mA.

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 16ns at V_CC = 5V and T_A = 25°C. Ensure your timing requirements can accommodate this delay.

5. Power Consumption:

   • The maximum power consumption (P_tot) is 200mW at V_CC = 5V. Ensure adequate heat dissipation if operating near this limit.

6. Temperature:

   • Store the device within the storage temperature range of -65°C to 150°C.
   • Operate the device within the operating temperature range of 0°C to 70°C to ensure reliable performance.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage sensitive components.
   • Follow proper soldering techniques and avoid excessive heat during installation.

8. Testing:

   • Before final assembly, test the device under typical operating conditions to verify its functionality.

By adhering to these parameters and instructions, you can ensure the reliable operation of the DM74ALS74AN dual D-type flip-flop.
