    Default ASK RF module to L293D connection

    After receiving the signal via the receiver, i want to connect the outputs of the decoder to a motor driver L293D, i checked out ratings of the pins and the l293D input pins allowed current in the microampere range, i found a circuit where they had a 10k resistor between the output of the decoder and the in put of the l293d, it would control the current but wouldnt that cause a drop in voltage, so wont the motordriver always read it as a low?

    the circuit is attached...
