AC ELECTRICAL CHARACTERISTICS
2
(VDD = 5.0V 10%; VSS = 0V
1, -55 C < T
C < +125 C)
Notes:
1. Maximum allowable relative shift equals 50mV.
2. All specifications valid for radiation dose
1E6 rads(Si).
3. Based on characterization, hold time (tH2) of 0ns can be assumed if data setup time (tSU2) is >10ns. This is guaranteed, but not tested.
