description
The SN74CBT162292 is a 12-bit 1-of-2
high-speed TTL-compatible 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
INT
is connected to port
B2. When S is high, port A is connected to port B2
and R
INT
is connected to port B1.
The A-port inputs/outputs include equivalent 25-Ω
series resistors to reduce overshoot and
undershoot.
The SN74CBT162292 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.
