AC CHARACTERISTICS READ CYCLE (Pre and Post-Radiation)*

(-55

°C to +125°C for (C) screening and -40°C to +125°C for (W) screening, V

Notes:

* Post-radiation performance guaranteed at 25

°C per MIL-STD-883 Method 1019.

1. Guaranteed, but not tested.

2. Three-state is defined as a 200mV change from steady-state output voltage.

3. The ET (enable true) notation refers to the latter falling edge of EN. SEU immunity does not affect the read parameters.

4. The EF (enable false) notation refers to the latter rising edge of EN. SEU immunity does not affect the read parameters.
