SN74CBT16390DL

The SN74CBT16390DL is a 16-bit to 32-bit FET multiplexer/demultiplexer Bus Switch used in applications in which two separate data paths must be multiplexed onto or demultiplexed from, a single path. This device can be used for memory interleaving, in which two different banks of memory must be addressed simultaneously. This device also can be used to connect or isolate the PCI bus to one or two slots simultaneously. Two output enables (OE1\ and OE2\) control the data flow. When OE1\ is low, A port is connected to 1B port. When OE2\ is low, A port is connected to 2B port. When both OE1\ and OE2\ are low, the A port is connected to both 1B and 2B ports. The control inputs can be driven with a 5V CMOS, 5V TTL or an LVTTL driver.
