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.
This device is designed so it does not have
through current when switching directions.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.

‡ This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
§ Measured by the voltage drop between A and B terminals at the indicated current through the switch. On-state resistance is determined by the
lower of the voltages of the two (A or B) terminals.
