6 / 13 page TC74HC123AP/AF 2012-02-29 6 Absolute Maximum Ratings (Note 1) Characteristics Symbol Rating Unit Supply voltage range VCC −0.5 to 7 V DC input voltage VIN −0.5 to VCC + 0.5 V DC output voltage VOUT −0.5 to VCC + 0.5 V Input diode current IIK ±20 mA Output diode current IOK ±20 mA DC output current IOUT ±25 mA DC VCC/ground current ICC ±50 mA Power dissipation PD 500 (DIP) (Note 2)/180 (SOP) mW Storage temperature Tstg −65 to 150 °C Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW. Operating Ranges (Note 1) Characteristics Symbol Rating Unit Supply voltage VCC 2 to 6 V Input voltage VIN 0 to VCC V Output voltage VOUT 0 to VCC V Operating temperature Topr −40 to 85 °C Input rise and fall time ( CLR only) tr, tf 0 to 1000 (VCC = 2.0 V) 0 to 500 (VCC = 4.5 V) 0 to 400 (VCC = 6.0 V) ns External capacitor Cx No limitation (Note 2) F External resistor Rx ≥5 k (VCC = 2.0 V) (Note 2) ≥1 k (VCC ≥ 3.0 V) (Note 2) Ω Note 1: The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND. Note 2: The maximum allowable values of Cx and Rx are a function of leakage of capacitor Cx, the leakage of TC74HC123A, and leakage due to board layout and surface resistance. Susceptibility to externally induced noise signals may occur for Rx > 1 MΩ. |
