3 / 7 page ![]() U74AHCT1G66 CMOS IC UNISONICTECHNOLOGIESCO.,LTD 3 of 7 www.unisonic.com.tw QW-R126-001.B ABSOLUTE MAXIMUM RATINGS (unless otherwise specified)(Note 1) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~7 V Enable Input Voltage VE -0.5~7 V Enable Input Clamp Current IEK -20 mA Switch Diode Current ISK ±20 mA On-State Switch current (-0.5V<VOS<VCC+0.5V) IS ±25 mA VCC or GND Current ICC ±75 mA Power Dissipation PD 250 mW Storage Temperature TSTG -65 ~ +150 °С Notes: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. 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. 3. To avoid drawing VCC current out of pin Z, when switch current flows into pin Y, the voltage drop across the bidirectional switch must not exceed 0.4V. If the switch current flows into pin Z, no VCC current will flow out of pin Y. In this case there is no limit for the voltage drop across the switch, but the voltage at pins Y and Z may not exceed VCC or GND.
