Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) 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 (VIL): 0.8V or less
      • High level (VIH): 2.0V or more
  3. Output Signals:

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

    • The propagation delay time (tpd) is typically 12 ns under standard conditions (VCC = 5V, TA = 25°C).
  5. Thermal Considerations:

    • The maximum power dissipation (PD) is 500 mW. Ensure proper heat sinking if operating near this limit.
    • The operating temperature range (TA) is from -40°C to 85°C.
    • The storage temperature range (TSTG) 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.
