Instructions for Use:

1. Power Supply:

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

2. Input Signals:

   • For a logic low input, the voltage should be less than or equal to 0.8 V.
   • For a logic high input, the voltage should be greater than or equal to 2.0 V.

3. Output Signals:

   • When the output is low, the voltage will be between 0.25 V and 0.4 V.
   • When the output is high, the voltage will be between 4.75 V and 5.0 V.

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 18 ns at V_CC = 5.0 V and T_A = 25°C, with a maximum of 35 ns.

5. Power Dissipation:

   • The maximum power dissipation per package is 100 mW. Ensure proper heat management if operating near this limit.

6. Temperature Ranges:

   • The device operates reliably over a temperature range of -40°C to 85°C.
   • Store the device in a temperature range of -65°C to 150°C.

7. Handling:

   • Handle the device with care to avoid static damage. Use appropriate ESD protection measures.
   • Follow recommended soldering and mounting procedures to ensure reliable operation.

8. Application Notes:

   • The 74HCT393 is a dual 4-bit binary counter with separate clock inputs. It can be used in various digital circuits for counting, timing, and control applications.
   • Ensure that all unused inputs are tied to a known state (either V_CC or GND) to prevent floating inputs, which can cause unpredictable behavior.
