The MX0141K High-Speed MUX is comprised of a high-speed 1:4 multiplexer (mux) path and a low-speed multi-function control logic path.

The high-speed path is comprised of four passive switches that connects input port “IN” to four output ports “A”, “B”, “C” and “D”. Each of those ports is 16-bit. The passive switches, which closed selectively, forms a bidirectional multiplexer.

The low-speed path is active multi-function IOs that could be configured in different modes. It could configured as unidirectional 1:4 mux with 4-bit port width, 4:16 decoder, or 16-bit signals for port selection. The CIO pins which can be used to drive Chip Enable pins of the NAND Dies, or high-speed mux selector. Both high-speed and low-speed paths support SSTL_12 and SSTL_18 signaling.
