SN74LVC1G126: Static power dissipation solution

Part Number: SN74LVC1G126
Other Parts Discussed in Thread: SN74LVC1G17

Hi

My customer is using a Vcc/2 bias at the input and AC coupling a signal. Based on the FAQ thread the input stage will partially turn on and increase leakage current. To solve this can we use a Schmidt trigger IC like SN74LVC1G17. can the Input pin be biased at Vcc/2 in a CMOS Schmidt trigger IC without increasing the current consumption. 

Regards,

Akshat

    No -- if they want to use the device as an analog amplifier/comparator, then they will have to use a standard buffer or inverter. This will always cause excessive power consumption.

    To achieve this function without a huge power spike, try an opamp or comparator.
