Abstract

A controlled slew rate buffer is disclosed which comprises a driver receiving voltage along a voltage supply line and includes feedback apparatus which senses the noise level along the voltage supply line and slows the speed of the buffer when the noise level passes a given threshold. The driver comprises at least one of (1) first and second VSS voltage sources and (2) first and second VDD voltage sources.
