发明名称 Bidirectional logic isolation multiplexing with voltage level translation capability for open-drain circuitry
摘要 Voltage level translation for open-drain circuitry is described. A logic isolation circuit includes a first buffer circuit configured for being switched between a first voltage transferable state and a first voltage non-transferable state. A first latch circuit is configured for being switched between a first reset state and a first non-reset state, the first reset state for setting the first latch circuit to a first reset condition. A second buffer circuit and second latch circuit are configured like the first buffer circuit and the first latch circuit. First and second input/output nodes are coupled to receive first and second logic level voltages, respectively. The first logic level voltage and the second logic level voltage are both for a same logic state, but the second logic level voltage is significantly greater than the first logic level voltage.
