Dear all,Does the MAX Vin specified for sn74lvc08 (5.5V) applies only when VCC= 5.5V or within the whole range of VCC.Thanks in advance.Nuba
Hi,
this part is LVC and no little logic, hence you must not apply a VCC of greater 3.6 V. (datasheet: operates from 1.65 V to 3.6 V). But the inputs are alway, independent of VCC 5 V tolerant (datasheet: inputs accept voltages to 5.5 V).

Sorry I meant SN74LV08A-EP.
Can its input go 5V while VCC is 4 V, for example?
Yes, it can. The input can go to 5V even if Vcc is zero. Check the Ioff feature.
