Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the specified range of 2.0V to 6.0V.
2. Input Handling: Do not exceed the maximum input voltage, which should be no more than VCC + 0.5V.
3. Output Load: Limit the output current to 卤25mA per output pin to avoid damage.
4. Thermal Considerations: Keep the device within its operating temperature range (-40掳C to 85掳C) to ensure reliable operation.
5. Storage Conditions: When storing the device, maintain temperatures between -65掳C and 150掳C.
6. Application: This IC is used as a decimal-to-7-segment decoder, converting binary-coded decimal inputs into signals that drive 7-segment displays. Connect the appropriate BCD inputs (A, B, C, D) to the corresponding pins on the IC to achieve the desired display output.
