Instructions for SN74AC244PW

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the specified range of 2.0V to 5.5V.

2. Output Drive Current:

   • For high output (IOH), the current should not exceed -4mA at VCC = 5V and VO = 2.7V.
   • For low output (IOL), the current can go up to 16mA at VCC = 5V and VO = 0.4V.

3. Propagation Delay:

   • The typical propagation delay time (tpd) is 3.9ns when VCC = 5V and input voltage (VI) is VCC/2.

4. Power Dissipation:

   • Keep the power dissipation per package below 480mW to avoid overheating and potential damage.

5. Handling Precautions:

   • Use appropriate ESD protection measures when handling the device.
   • Avoid exceeding the maximum ratings as it can lead to permanent damage.

6. Application Considerations:

   • This device is suitable for bus interface applications where buffering and level translation are required.
   • Ensure all unused inputs are tied to a defined logic level to prevent floating states.
