DESCRIPTION
The CBT16292 is a 12-bit 1-of-2 high-speed TTL-compatible
multiplexer/demultiplexer. The low on-state resistance of the switch
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
is connected to port B2. When S is high, port A is connected to
INT
port B2 and R
The CBT162292 is characterized for operation from –40°C to +85°C.
is connected to port B1.
