Abstract: A current transition rate control circuit is provided, comprising first and second data inputs; first and second charge/discharge circuits for receiving the first and second data inputs; a first reference voltage circuit for sending a first control signal and a second reference voltage circuit for sending a second control signal to, respectively, the first and second charge/discharge circuits; and first and second output transistors coupled, respectively, to the outputs of the first and second charge/discharge circuits. The circuit controls the switching speed of the output transistors to minimize current spikes on the output. The circuit may include a pre-driver circuit for (i) receiving a single data input and outputting the first and second data inputs, and (ii) receiving a circuit disabling signal and placing the circuit in a high impedance state which turns off both of the output transistors.
