Patent ID: 7208984

Claim:
A break-before-make circuit, comprising: a first logic element having an enabled state and a disabled state, the first logic element further having an output, and being configured to invert a signal input and provide the inverted signal input to its output in the enabled state, the first logic element further being configured to float its output in the disabled state when the signal input transitions to a first logic state; a second logic element having an enabled state and a disabled state, the second logic element further having an output, and being configured to invert a signal input and provide the inverted signal input to its output in the enabled state, the second logic element further being configured to float its output in the disabled state when the signal input transitions to a second logic state, the second logic state having a higher voltage than the first logic state; a first inverter having an input coupled to the output of the first logic element, and an output, the state of the second logic element being responsive to the first inverter output; and a second inverter having an input coupled to the output of the second logic element, and an output, the state of the first logic element being a responsive to the second inverter output.
