Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.75V to 5.25V.
   • Connect the ground (GND) pin to a stable ground reference.

2. Input Signals:

   • Input signals should be within the valid logic levels:
     • Low level (V_IL): 0.8V or less
     • High level (V_IH): 2.0V or more

3. Output Signals:

   • When driving loads, ensure the output current does not exceed the specified limits:
     • Output low (V_OL): 0.3V at 16 mA
     • Output high (V_OH): 4.5V at -4 mA

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically 12 ns under standard conditions (V_CC = 5V, T_A = 25°C).

5. Thermal Considerations:

   • The maximum power dissipation (P_D) is 500 mW. Ensure proper heat sinking if operating near this limit.
   • The operating temperature range (T_A) is from -40°C to 85°C.
   • The storage temperature range (T_STG) is from -65°C to 150°C.

6. Handling and Storage:

   • Handle the device with care to avoid static damage.
   • Store the device in a dry environment within the specified storage temperature range.

7. Directional Control:

   • Use the direction control pins (DIR) to set the direction of data transfer between the two sets of 8-bit buses.

8. Enable/Disable:

   • Use the output enable (OE) pin to control whether the outputs are active or in a high-impedance state.
