Notes: * Post-radiation performance guaranteed at 25 °C per MIL-STD-883 Method 1019.
1. Functional test.
2. Three-state is defined as a 300mV change from steady-state output voltage.
3. The ET (enable true) notation refers to the falling edge of En. SEU immunity does not affect the read parameters.
4. The EF (enable false) notation refers to the rising edge ofEn. SEU immunity does not affect the read parameters.
