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
10B1, 10B2 Outputs
11B1, 11B2 Outputs
12B1, 12B2 Outputs
INT
port B2 and R
is connected to port B1.

The CBT162292 is characterized for operation from –40°C to +85°C.

NOTES:
1. Stresses beyond those listed 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.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTE:
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
2. Time interval between break and make measured at the same operating point (V and temperature).
