Instructions for Use:

1. Power Supply:

   • Ensure that the supply voltage (Vcc) is within the specified range of 4.5V to 5.5V.
   • Connect the ground (GND) pin to a stable ground reference.

2. Signal Timing:

   • The device has an access time of 20ns. Ensure that the clock or control signals are stable and meet this timing requirement.
   • Use appropriate pull-up or pull-down resistors on control lines if necessary.

3. Current Considerations:

   • The active current consumption is 30mA. Design the power supply to handle this load.
   • The standby current is 20μA, which is useful for low-power applications.

4. Temperature Range:

   • The device is rated for commercial temperature range (0°C to 70°C). Ensure that the operating environment does not exceed these limits.
   • For extended storage, keep the device within the storage temperature range (-65°C to 150°C).

5. Package Handling:

   • Handle the 28-Pin PDIP package with care to avoid damage to the pins.
   • Follow proper ESD (Electrostatic Discharge) handling procedures to prevent damage to the device.

6. Output Drive:

   • The output drive capability is 16mA. Ensure that the connected loads do not exceed this limit to avoid damaging the device.

7. Testing and Verification:

   • After installation, verify the functionality of the device by performing read and write operations and checking the data integrity.

8. Documentation:

   • Refer to the datasheet for detailed information on pin configurations, timing diagrams, and other technical specifications.
