Switch Connection Between Two PortsWidebus is a trademark of Texas Instruments.
The SN74CBT16233 is a 16-bit 1-of-2 FET multiplexer/demultiplexer 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, where two different banks of memory need to be addressed simultaneously. The device can be used as two 8-bit to 16-bit multiplexers or as one 16-bit to 32-bit multiplexer.
Two select (SEL1 and SEL2) inputs control the data flow. When the TEST inputs are asserted, the A port is connected to both the B1 and the B2 ports. SEL1, SEL2, and the TEST inputs can be driven with a 5-V CMOS, a 5-V TTL, or a low-voltage TTL driver.
This device is designed so it does not have through current when switching directions.
