Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the specified range of 1.65V to 5.5V.
2. Signal Levels: For reliable operation, ensure that the input signals do not exceed the supply voltage and are not less than ground potential.
3. Decoupling Capacitors: Place decoupling capacitors close to the power supply pins to minimize noise and transient effects.
4. Propagation Delay: Account for the propagation delay in timing-sensitive applications. The typical delay is 4.8 ns at VCC = 3.3V.
5. Output Drive Capability: The device can drive up to 16 mA at low output level while maintaining a maximum VOL of 0.2V.
6. Temperature Range: Ensure the operating temperature stays within the industrial range (-40掳C to +85掳C).
7. Storage and Handling: Follow standard ESD precautions when handling the device to prevent damage.

Note: Always refer to the manufacturer's datasheet for the most accurate and detailed information specific to your application requirements.
