Limiting values

[1]

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

[2]

VCCO is the supply voltage associated with the output port.

[3]

VCCO + 0.5 V should not exceed 4.6 V.

[4]

For SO16 package: above 70

C derates linearly with 8 mW/K.

For TSSOP16 package: above 60

C the value of P

tot derates linearly at 5.5 mW/K.

For DHVQFN16 package: above 60

C the value of P

tot derates linearly at 4.5 mW/K.

[5]

For XQFN16 package: above 133

C the value of P

tot derates linearly with 14.5 mW/K.

Recommended operating conditions

[1]

VCCO is the supply voltage associated with the output port.

[2]

VCCI is the supply voltage associated with the input port.

Table 5.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
