NXP Semiconductors 74HC590 8-bit binary counter with output register; 3-state 7. Limiting values Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
Symbol Parameter Conditions Min Max Unit
VCC supply voltage −0.5 +7.0 V IIK input clamping current VI < −0.5 V or VI > VCC + 0.5 V [1] - ±20 mA IOK output clamping current VO < −0.5 V or VO > VCC + 0.5 V [1] - ±20 mA IO output current VO = −0.5 V to VCC + 0.5 V RCO standard output - ±25 mA Qn bus driver output - ±35 mA ICC supply current - 70 mA IGND ground current −70 - mA Tstg storage temperature −65 +150 °C Ptot total power dissipation Tamb = −40 °C to +125 °C [2] DIP16 package - 750 mW SO16 package - 500 mW TSSOP16 package - 500 mW [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] For DIP16 package: Ptot derates linearly with 12 mW/K above 70 °C. For SO16 packages: Ptot derates linearly with 8 mW/K above 70 °C. For TSSOP16 packages: Ptot derates linearly with 5.5 mW/K above 60 °C. For DHVQFN16 packages: Ptot derates linearly with 8 mW/K above 60 °C.
