Product data sheet Rev. 03 — 23 May 2007 8 of 29 NXP Semiconductors 74HC193; 74HCT193 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).
