Instructions for Using SN74LS393:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 4.75V to 5.25V.
- Connect VCC to the positive power supply and GND to the ground.
Input Signals:
- Apply logic high (VIH) signals greater than 2.0V.
- Apply logic low (VIL) signals less than 0.8V.
- Ensure input currents do not exceed the specified limits.
Output Signals:
- Logic high (VOH) output will be at least 2.4V when sourcing up to -0.4 mA.
- Logic low (VOL) output will be no more than 0.5V when sinking up to 16 mA.
Propagation Delay:
- The propagation delay time (tpd) is typically 22 ns under standard conditions (VCC = 5V, TA = 25°C).
Power Consumption:
- The device typically consumes 100 mW under standard operating conditions.
Handling:
- Handle the IC with care to avoid static damage.
- Ensure all connections are secure and free from short circuits.
Storage:
- Store the IC in a dry, cool place to prevent moisture damage.
Application:
- The SN74LS393 is a dual 4-bit binary counter, suitable for applications requiring counting or frequency division.
