General Description
The VS3V257 is a high-speed LVTTL–compatible Quad 2:1 multiplexer/demultiplexer. The VS3V257
contains four mux/demux channels, with a common path control (S) and active low enable (/E). The low ON
resistance of the VS3V257 allows inputs to be connected to outputs, without adding propagation delay and
without generating additional signal noise. The VS3V2257 has 25
resistors in series with the switches to
reduce ground-bounce noise and signal reflection.
The VS3V257 and VS3V2257 are designed for 3.3V to 2.5V or 2.5V to 1.8V level translation, without any
external components. These switches also offer very high impedance between switch terminals in the
power-off or “disabled” state. This feature, combined with near-zero propagation delay in the “on” state,
makes VS3V257 and VS3V2257 ideal interface elements for hot-swapping applications.
