Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] For SO16 packages: above 70 °C the value of P tot derates linearly at 8 mW/K. For TSSOP16 packages: above 60 °C the value of P tot derates linearly at 5.5 mW/K. 8. Recommended operating conditions Table 4. Operating mode select table[1] LE MR Mode L H addressable latch H H memory L L active HIGH 8-channel demultiplexer H L reset Table 5. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
