Instructions for Using the MC74HC157AN

1. Power Supply:

   • Ensure that the supply voltage (V_CC) is within the operating range of 2.0V to 6.0V.
   • Connect V_CC to the positive power supply and GND to the ground.

2. Input Signals:

   • The input low voltage (V_IL) should be no higher than 0.8V when V_CC is between 4.5V and 5.5V.
   • The input high voltage (V_IH) should be at least 2.0V under the same conditions.

3. Output Signals:

   • When the output is low (V_OL), it should not exceed 0.2V with a load current of 4 mA.
   • When the output is high (V_OH), it should be at least 4.4V with a load current of -4 mA.

4. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for the output to change after the input changes. It should be between 6 ns and 12 ns at room temperature (25°C) and with V_CC between 4.5V and 5.5V.

5. Power Dissipation:

   • The maximum power dissipation (P_D) is 100 mW. Ensure that the device does not exceed this limit to avoid overheating and potential damage.

6. Temperature Ranges:

   • The operating temperature range (T_A) is from -40°C to 85°C.
   • The storage temperature range (T_STG) is from -65°C to 150°C. Store the device in a dry and cool place to prevent damage.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Use appropriate ESD (Electrostatic Discharge) protection measures during handling and installation.

8. Pin Configuration:

   • Refer to the pinout diagram provided in the datasheet to correctly connect the device to your circuit.

9. Testing:

   • Before integrating the device into a larger system, test it individually to ensure it meets the specified parameters and functions correctly.

10. Compliance:

    • Ensure that the device complies with all relevant safety and regulatory standards for your application.
