AC CHARACTERISTICS READ CYCLE (Pre/Post-Radiation)*
(VDD = 5.0V±10%) (-55°C to +125°C)
Notes: * Post-radiation performance guaranteed at 25
°C per MIL-STD-883 Method 1019.
1. Functional test.
2. Three-state is defined as a 500mV change from steady-state output voltage.
3. The ET (enable true) notation refers to the falling edge of E1. SEU immunity does not affect the read parameters.
4. The EF (enable false) notation refers to the rising edge of E1. SEU immunity does not affect the read parameters.
