Octal D-type flip-flop with data enable; positive-edge trigger

6. Functional description

Table 3. Function table

H = HIGH voltage level; h = HIGH voltage level one set-up time prior to the LOW to HIGH CP transition

L = LOW voltage level; l = LOW voltage level one set-up time prior to the LOW to HIGH CP transition

↑ = LOW to HIGH CP transition; NC = no change; X = don’t care

[1] The minimum input voltage ratings may be exceeded if the input current ratings are observed.

[2] The output voltage ratings may be exceeded if the output current ratings are observed.

[3] For SOT163-1 (SO20) package: Ptot derates linearly with 12.3 mW/K above 109 °C.

For SOT360-1 (TSSOP20) package: Ptot derates linearly with 10.0 mW/K above 100 °C.
