FEATURES
DESCRIPTION
The CBTD3257 is a quad 1-of-2 high-speed TTL-compatible
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.
Output Enable (OE) and select-control (S) inputs select the
appropriate B1 and B2 outputs for the A-input data.
Internal diode allows voltage level shifting from 5 V inputs to 3.3 V
outputs.
The CBTD3257 is characterized for operation from –40 to +85 C.
