CBT3253A
Dual 1-of-4 FET multiplexer/demultiplexer
Rev. 5 — 9 May 2017
Product data sheet
1 General description
The CBT3253A 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.
When the output enable input (nOE) is LOW, the 1-of-4 multiplexer/demultiplexer is
enabled. The data path is selected by the select control inputs (S0, S1). When nOE is
HIGH, the 1-of-4 multiplexer/demultiplexer is disabled. The switch terminals are in the
high impedance OFF-state, independent of S0 and S1.
The CBT3253A is characterized for operation from -40 °C to +85 °C.
