description
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.
The device is specified by design not to have
through current when switching directions.
The SN74CBT16233 is characterized for
operation from 0°C to 70°C.
