Functional description

[1]

H = HIGH voltage level;

L = LOW voltage level;

↑ = LOW-to-HIGH CP transition;

X = don’t care;

q = lower case letter indicates the state of referenced input, one setup time prior to the LOW-to-HIGH CP transition.

8.

Limiting values

[1]

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

[2]

For TSSOP5 and SC-74A packages: above 87.5

°C the value of P

For XSON6 packages: above 118

°C the value of P
