Note 1:
Specifications
≥+25°C guaranteed by production test, <+25°C guaranteed by design and characterization.
Note 2:
Specifications guaranteed by design and characterization. Devices tested for performance during production test.
Note 3:
Guaranteed by design and characterization.
Note 4:
During power-down, D11–D0, DOR, and DAV are high impedance.
Note 5:
Digital outputs settle to V
