... I/O pins with the data word referenced by the input address. When either chip enable or output enable is inactive, or write enable is active, output drivers stay in high-impedance mode. All chip inputs and outputs are TTL-compatible, and operation is from a single 5V supply (AS7C1025) or 3.3V supply (AS7C31025). The AS7C1025 and AS7C31025 are packaged in common industry standard packages. ...
