Other Parts Discussed in Thread: SN74AUP1G17, SN74LVC1G123, TS5A23157-Q1
Hi all
My customer is looking at the SN74LVC1G17 and they find the input bias current max values of +/-5uA are a problem in their application.
They have an RC in front of this schmitt trigger to generate a large and accurate time constant (safety function), therefore they have to use a COG/NPO capacitor and a large resistor as larger value COG/NPO capacitors are not available or would be too bulky / too expensive. In this situation the +/-5uA affect the accuracy of the time constant.
Can you comment as to the reason for this large tolerance ? ... and comment as what the conditions are when to expect these max values ?
Can you recommend another solution or another device with a lower value for max input current ?
Best regards
Ueli
