3 / 5 page U74HCT245 CMOS IC UNISONICTECHNOLOGIESCO.,LTD 3 of 5 www.unisonic.com.tw QW-R502-646.B ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~7.0 V Input Clamp Current (ViN<0) IIK ±20 mA Output Clamp Current (VOUT<0) IOK ±20 mA Output Current IOUT ±35 mA VCC or GND Current ICC ±70 mA Storage Temperature TSTG -65 ~ +150 °C Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
