Instructions for Use

1. Power Supply: Connect Vcc to the positive supply voltage (2.5V to 6.0V) and Vss to ground.
2. Address Lines: Apply the desired address to the address lines (A0 to A14).
3. Data Lines: Data is read from or written to the data lines (D0 to D7).
4. Control Signals:
   • /CE1 (Chip Enable 1): Set low to enable the device.
   • /OE (Output Enable): Set low to enable data output.
   • /WE (Write Enable): Set low to write data to the selected address.
5. Temperature Considerations: Ensure the operating temperature is within the specified range (-40掳C to +85掳C).
6. Handling: Handle with care to avoid damage to the pins and the chip.
