10-bit D-type flip-flop with 5 V tolerant inputs/outputs
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO24 package: above 70 °C derate linearly with 8 mW/K.
For SSOP24 and TSSOP24 packages: above 60 °C derate linearly with 5.5 mW/K.
For DHVQFN24 package: above 60 °C derate linearly with 4.5 mW/K.
