7.0 DC OUTPUT ELECTRICAL CHARACTERISTICS (Pre- and Post-Radiation)*
(VDDQn = +2.5V + 10%; VDD = +3.3V + 0.3V; TC = -55°C to +125°C) (For "W" screening, TC = -40°C to +125°C) (Note 1)
Notes: * Post-radiation performance guaranteed at 25
°C per MIL-STD-883 Method 1019, Condition A up to a TID level of 1.0E6 rad(Si).
1. Unless otherwise noted, these tests are performed with VDD and VDDQn at their minimum levels.
2. Supplied as a design limit. Neither guaranteed nor tested.
3. When measuring the dynamic supply current, all outputs are loaded in accordance with the equivalent test load defined in figure 10.
4. Capacitance is measured for initial qualification and when design changes may affect the input/output capacitance. Capacitance is measured between the designated
terminal and VSS at a frequency of 1MHz and a signal amplitude of 50mV rms maximum.
5. For the UT7R995, the 200MHz test condition is based on an XTAL1 frequency of 200MHz. For the UT7R995C, the 200MHz test condition is based on an XTAL1
frequency of 16.666667MHz, and a N-divider setting of 12.
6. To reduce power consumption for the device, the user may tie the unused VDDQn pins to VSS.
