Instructions for Use:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.
- Connect the ground (GND) pin to a stable 0V reference.
Input Signals:
- Input voltages should be within the specified range to avoid damage or incorrect operation.
- For a logic low, the input voltage should be less than 0.8V.
- For a logic high, the input voltage should be greater than 2.0V (or VCC if VCC < 2.0V).
Output Signals:
- The output voltage (VOH) when high should be at least 4.1V for VCC = 4.5V and 4.7V for VCC = 5.5V.
- The output voltage (VOL) when low should be no more than 0.9V for VCC = 4.5V and 1.0V for VCC = 5.5V.
- Ensure the load current does not exceed the maximum output current ratings.
Propagation Delay:
- The propagation delay time (tpd) is typically 12ns under standard conditions. This is important for timing considerations in your circuit design.
Temperature Considerations:
- The device is rated for operation over a temperature range of -40°C to 85°C.
- Store the device in an environment where the temperature does not exceed -65°C to 150°C.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal circuits.
- Follow proper ESD (Electrostatic Discharge) precautions during handling and installation.
Mounting:
- Ensure proper mounting and soldering techniques to avoid mechanical stress on the package.
- Use appropriate thermal management techniques if operating near the maximum power dissipation limit.
