Power Supply Connection: Connect the supply voltage (Vcc) between pin 14 and ground (pin 7). Ensure that the supply voltage is within the specified range of 4.75 V to 5.25 V.
Input Connections: Connect your input signals to pins 1, 2, 4, 5, 9, 10, 12, and 13. These pins correspond to the inputs of the four AND gates.
Output Connections: The outputs are located on pins 3, 6, 8, and 11. These are open collector outputs, so you may need pull-up resistors depending on your application.
Handling Precautions: Handle the device carefully to avoid damage from electrostatic discharge (ESD). Use appropriate ESD protection measures when handling or soldering the component.
Temperature Considerations: Ensure that the operating temperature remains within the specified range of 0°C to 70°C to maintain reliable operation.
Storage Conditions: Store the device in a dry place with temperatures not exceeding the storage temperature range of -65°C to 150°C.
Application Notes: Refer to the datasheet for detailed application notes and timing diagrams to ensure proper integration into your circuit design.
