Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 2.0 V to 6.0 V.
   • Connect the ground (GND) pin to a stable reference ground.

2. Input Signals:

   • Apply input signals that comply with the input voltage levels:
     • Low input (V_IL): -0.5 V to V_CC - 1.5 V
     • High input (V_IH): V_CC - 1.5 V to V_CC + 0.5 V

3. Output Signals:

   • The output will be low (V_OL) when the inputs are not equal, with a maximum voltage of 0.4 V at 4 mA.
   • The output will be high (V_OH) when the inputs are equal, with a minimum voltage of 2.4 V at -4 mA.

4. Current Handling:

   • Ensure that the input and output currents do not exceed the specified limits to avoid damage to the device.
   • Input leakage current (I_IL) should be within ±1.0 μA.
   • Output leakage current (I_OL) should be within ±1.0 μA.

5. Propagation Delay:

   • The maximum propagation delay time (t_pd) is 10 ns, which should be considered in timing-critical applications.

6. Power Management:

   • The device can dissipate up to 100 mW of power. Ensure adequate heat dissipation if operating near this limit.

7. Storage and Handling:

   • Store the device in a dry, static-free environment.
   • Handle with care to avoid damage from electrostatic discharge (ESD).

By following these guidelines, you can ensure reliable operation of the MM74HC688WM in your circuit.
