Note 2: Unless otherwise specified all voltages are referenced to ground. Note 3: Power Dissipation temperature derating — plastic “N” package: 12 mW/ qC from 65qC to 85qC. DC Electrical Characteristics (Note 4) Note 4: For a power supply of 5V r10% the worst case output voltages (VOH, 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 VCC 1.5V DC Output Voltage (VOUT) 0.5 to VCC 0.5V Clamp Diode Current (IIK, IOK) r20 mA DC Output Current, per pin (IOUT) r25 mA DC VCC or GND Current, per pin (ICC) r50 mA Storage Temperature Range (TSTG) 65qC to 150qC Power Dissipation (PD) (Note 3) 600 mW S.O.
