DESCRIPTION
SA00574
The CBT3253 is a dual 1-of-4 high-speed TTL-compatible FET
multiplexer/demultiplexer. The low on resistance of the switch allows
inputs to be connected to outputs without adding propagation delay
or generating additional ground bounce noise.
PIN DESCRIPTION
1OE, 2OE, S0, and S1 select the appropriate B output for the
A-input data.
The CBT3251 is characterized for operation from –40 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 input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

NOTES:
1. All typical values are at VCC = 5 V, Tamb = 25 °C.
2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch.
On-state resistance is determined by the lowest voltage of the two (A or B) terminals.
