Part Number: SN74LV14A
Hi allWould you mind if we ask SN74LV14A?How much is input impedance in case of Vcc=5.0V? 5V(VCC)/12mA(IOH)?Kind regards,Hirotaka Matsumoto
I am a little confused -- you want to know how the input impedance changes based on the output current?
This is a CMOS logic gate -- the input impedance will always be very large, based on the leakage current at the input given in the datasheet:
Input capacitance (typical, to ground): 2.3 pF, given in datasheet at Ci
Input resistance (minimum, to ground): 5.5 MΩ, calculated from datasheet value Ii and the supply voltage
Neither of these values is related to the output current.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
