A low noise buffer circuit for increasing the slew rates of transitions between signal states of a digital signal while drawing minimal transient power supply current during such signal state transitions. Successive alternating digital signal inversion circuits conduct respective power supply source and sink currents which: are unregulated source currents and regulated sink currents during respective low-to-high output signal transitions; transition from unregulated source currents and regulated sink currents to regulated source currents and unregulated sink currents, respectively, during respective high output signal states; are regulated source currents and unregulated sink currents during respective high-to-low output signal transitions; and transition from regulated source currents and unregulated sink currents to unregulated source currents and regulated sink currents, respectively, during respective low output signal states.
