5 / 10 page 5 www.fairchildsemi.com Absolute Maximum Ratings(Note 1) (Note 2) Recommended Operating Conditions Note 1: Maximum Ratings are those values beyond which damage to the device may occur. Note 2: Unless otherwise specified all voltages are referenced to ground. Note 3: Power Dissipation Temperature Derating: Plastic “N” Package: − 12mW/ °C from 65°C to 85°C. DC Electrical Characteristics (Note 4) Note 4: For a power supply of 5V ±10% the worst case output voltages (V OH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage cur- rent (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. Supply Voltage (VCC) −0.5 to +7.0V DC Input Voltage (VIN) −1.5 to V CC +1.5V DC Output Voltage (VOUT) −0.5 to V CC +0.5V Clamp Diode Current (IIK, IOK) ±20 mA DC Output Current, per pin (IOUT) ±25 mA DC VCC or GND Current, per pin (ICC) ±50 mA Storage Temperature Range (TSTG) −65°C to +150°C Power Dissipation (PD) (Note 3) 600 mW S.O.
