Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at T
A
= +25°C.
Note 3: Parameters are guaranteed by design and characterization and are not production tested. Limits are set at ±6 sigma.
Note 4: All LVTTL/LVCMOS inputs, except PWRDWN at ≤ 0.3V or ≥ V
CCIN
- 0.3V. PWRDWN is ≤ 0.3V.
