The SN74CB3T3257 is used to multiplex and demultiplex up to 4 channels simultaneously in a 2:1 configuration. The application shown here is a 4-bit bus, multiplexed between two devices. The OE and S pins are used to control the chip from the bus controller. This is a generic example, and can apply to many situations. If an application requires less than 4 bits, tie the A side to either high or low on unused channels.
