hi everyone
i intend multiplexing two 7 common anode segment displays with a port of a micro controller by making 7 pins common to both of them and then the last one for the multiplexing. i dont know if there is a transistor that can switch as fast as a micro controller . some one suggested to me FETs but i have not used them before. i have simulated it and it works well when the delay for the multiplexing is quite large and noticeable. at shorter delays it throws a simulation error
