Instructions for Use:

1. Supply Voltage (VCC):

   • Operate the device within the specified supply voltage range of 1.5V to 6.0V.

2. Input Signals:

   • Ensure input signals are within the defined low (0.0V to 0.8V) and high (2.0V to VCC) voltage levels to avoid undefined behavior.

3. Output Drive Capability:

   • The device can drive loads up to 8mA in the low state and sink up to 4mA in the high state while maintaining output voltage specifications.

4. Propagation Delay:

   • Account for propagation delays when designing timing-sensitive circuits. Delays can be up to 23ns at VCC=4.5V.

5. Power Dissipation:

   • Keep power dissipation below 100mW to prevent overheating and ensure reliable operation.

6. Operating Temperature:

   • The device is designed to operate reliably between -40掳C and 85掳C.

7. Handling Precautions:

   • This component is sensitive to electrostatic discharge (ESD). Handle with appropriate ESD precautions to prevent damage.

8. Application Considerations:

   • The 74AHCT08 is a quad 2-input AND gate suitable for use in digital logic circuits where TTL-compatible inputs and outputs are required.
