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
Hello Matsumoto-san,
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.
