description
The SN74CBTLV16292 is a 12-bit 1-of-2
high-speed FET multiplexer/demultiplexer. The
low on-state resistance of the switch allows
connections to be made with minimal propagation
delay .
When the select (S) input is low, port A is
connected to port B1 and R
port B2. When S is high, port A is connected to
port B2 and R
is connected to port B1.
INT
The SN74CBTLV16292 is characterized for
operation from –40°C to 85°C.

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.

This is the increase in supply current for each input that is at the specified voltage level rather than VCC or GND.

Measured by the voltage drop between the 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.
