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.
