TABLE 2: Functional Description
1. When UB and LB are in select mode (low), I/O
2. When the device is in standby mode, control inputs ( WE, OE , UB , and LB), address inputs and data input/outputs are internally
3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.
4. The device will consume active power in this mode whenever addresses are changed. Data inputs are internally isolated from any
