3 / 4 page 74HC123A Specification Number 74HC123-I (F) Rev C Page 3 of 4 3 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 (VOH, VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when design- ing 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 current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. Supply Voltage (VCC) −0.5V to +7.0V DC Input Voltage (VIN) −1.5V to VCC +1.5V DC Output Voltage (VOUT) −0.5V to VCC +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.
