SN74LVC1G123: Consumption Current

Sean Liao (Yu-Sheng)

Part Number: SN74LVC1G123


Hi, 

Could you please kindly suggest the Icc of SN74LVC1G123 at Vcc=3.3V?

Since the datasheet only shows the Icc=20uA at Vcc=5.5V but no data at 3.3V. 

Thanks a lot for your support!

    Hello,
    The value of 20uA is not the supply current at 5.5V, it is the maximum static supply current that any SN74LVC1G123 operating at any valid temperature or supply voltage could draw. The actual static supply value will likely be under 1uA for typical applications, however TI only guarantees the maximum in the datasheet.

    Are you attempting to determine the standby power draw of the device? If so, the correct method is to use the maximum value given in the datasheet -- thus ensuring your final system will have adequate power available for the device.
