Instructions:

1. Power Supply: Ensure the Vcc supply voltage is within the specified range of 4.5V to 5.5V.
2. Programming Voltage: Use a Vpp programming voltage of 12.5V ± 0.5V for writing data.
3. Access Time: The device has an access time of up to 150ns; ensure your system timing accounts for this delay.
4. Temperature Considerations: Operate the device within the temperature range of -40°C to +85°C to avoid damage or malfunction.
5. Programming: A typical programming cycle takes about 5ms. Do not exceed 100,000 program/erase cycles to maintain reliability.
6. Handling: Handle with care to prevent electrostatic discharge (ESD) damage. Use appropriate ESD protection measures.
7. Installation: Ensure the correct orientation when installing in a 28-Pin PDIP or 28-Pin PLCC socket.
8. Data Retention: Data retention is guaranteed for 10 years at 85°C; store in cooler environments for extended retention.
