Abstract
A circuit for providing a signal which enables the high impedance state of a subsequent three state circuit includes a first circuit portion which provides current to an output node to disable the high impedance state when an input signal is in the first state and a second circuit portion which sinks current from the output node to enable the high impedance state when the input signal is in a second state. The circuit includes an input stage which is directly coupled to a transistor, which transistor simultaneously enables said second circuit portion and disables said first circuit portion when the input signal switches from said second state to said first state.
