General Description
The VS3257 is a high-speed TTL–compatible Quad 2:1 multiplexer/demultiplexer. The VS3257 contains four
mux/demux channels, with a common path control (S) and active low enable (/E). The low ON resistance of
the VS3257 allows inputs to be connected to outputs, without adding propagation delay and without
generating additional signal noise. The VS32257 has 25
resistors in series with the switches to reduce
ground-bounce noise and signal reflection.
The VS3257 and VS32257 mux/demux switches are function and pinout compatible with QS3257 and
CBT3257 switches. They enable 5V to 3.3V translation when used with an external diode in the power supply
line. In addition, the high off-isolation in the ‘disable’ mode makes VS3257 and VS32257 ideal interface
elements for hot-swap applications.
