Instructions for Use
Power Supply:
- Connect the VCC pin to a stable 5V power supply.
- Ensure the ground (GND) pin is connected to the system ground.
Input Signals:
- Apply digital input signals to the input pins within the valid input voltage range (0V to VCC).
- Ensure signal transitions are clean and within the specified propagation delay.
Output Handling:
- The output pins can source up to 30mA and sink up to 50mA.
- Use appropriate external components (e.g., resistors, capacitors) to ensure stable operation and protection.
Temperature Considerations:
- Operate the device within the specified operating temperature range (-40°C to 85°C).
- Store the device within the storage temperature range (-65°C to 150°C).
Power Consumption:
- Monitor the quiescent current to ensure it remains within the typical value of 10μA at VCC = 5V.
Layout and Grounding:
- Use a good PCB layout with proper grounding to minimize noise and interference.
- Place decoupling capacitors close to the VCC and GND pins to filter out high-frequency noise.
Handling Precautions:
- Handle the device with care to avoid static discharge which can damage the internal circuits.
- Follow standard ESD (Electrostatic Discharge) precautions during handling and assembly.
