Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (4.75V to 5.25V).
   • Connect Vcc to the positive supply and GND to the ground.

2. Input Levels:

   • For logic high, input voltages should be between 2V and Vcc-0.5V.
   • For logic low, input voltages should be between 0V and 0.8V.

3. Output Levels:

   • When the output is high, the voltage should be between 2.4V and Vcc-0.5V.
   • When the output is low, the voltage should be between 0V and 0.5V.

4. Current Ratings:

   • Ensure that the input currents do not exceed the specified limits.
   • The output can source up to 8mA and sink up to 16mA.

5. Propagation Delay:

   • The propagation delay time is typically 27ns at 5V and 25°C. Ensure your timing requirements are met.

6. Temperature Considerations:

   • Operate the device within the specified temperature range (-55°C to 125°C).
   • Store the device within the storage temperature range (-65°C to 150°C).

7. Handling:

   • Handle the device with care to avoid static damage.
   • Follow proper soldering techniques to ensure reliable connections.

8. Application Notes:

   • The SN74LS193N is a 4-bit binary/decimal up/down counter with parallel load.
   • It has separate up and down count inputs, a parallel load input, and outputs for all four bits.
   • Use the reset and preset inputs to set the counter to a specific value.
