Presettable synchronous 4-bit binary up/down counter
7. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For DIP16 packages: above 70 C the value of P
tot
derates linearly at 12 mW/K.
For SO16 packages: above 70 C the value of P
tot
derates linearly at 8 mW/K.
For SSOP16 and TSSOP16 packages: above 60 C the value of P
tot
derates linearly at 5.5 mW/K.
8. Recommended operating conditions
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
