Instructions for Use:
- Power Supply: Ensure the supply voltage (VCC) is within the specified range of 2.0V to 6.0V.
- Input Handling: Do not exceed the maximum input voltage, which should be no more than VCC + 0.5V.
- Output Load: Limit the output current to ±25mA per output pin to avoid damage.
- Thermal Considerations: Keep the device within its operating temperature range (-40°C to 85°C) to ensure reliable operation.
- Storage Conditions: When storing the device, maintain temperatures between -65°C and 150°C.
- 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.
