4 / 12 page Philips Semiconductors Product specification 74LV688 8-bit magnitude comparator 1998 Jun 23 4 ABSOLUTE MAXIMUM RATINGS1, 2 In accordance with the Absolute Maximum Rating System (IEC 134). Voltages are referenced to GND (ground = 0V). SYMBOL PARAMETER CONDITIONS MIN MAX UNIT VCC DC supply voltage –0.5 +7.0 V IIK DC input diode current VI < –0.5 V or V1 > VCC + 0.5V – ± 20 mA IOK DC output diode current VO < –0.5 V or V0 > VCC + 0.5V – ± 50 mA IO DC output source or sink current – standard outputs –0.5V < VO < VCC +0.5V ± 25 mA ± IGND, ± ICC DC VCC or GND current for types with – standard outputs ± 50 mA Tstg Storage temperature range –65 +150 °C Ptot power dissipation per package – plastic DIL – plastic mini-pack (SO) – plastic medium-shrink SO (SSOP and TSSOP) for temperature range: –40 to +125 °C above +70 °C derate linearly with 12 mW/K above +70 °C derate linearly with 8 mW/K above +60 °C derate linearly with 5.5 mW/K – – – 750 500 400 mW NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability. 2. The performance capability of a high–performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
