Principio de funcionamiento
Two 4:1 multiplexer sections each select one of four I/O ports under 2-bit address control (S0, S1). CBTLV (crossbar technology) uses nFET pass gates with low 6 ohm ON resistance and 1 pC charge injection for minimal signal degradation. Break-before-make switching prevents momentary channel-to-channel shorts. OE input disables both sections.
