General Description
The VS3V253 is a high-speed LVTTL–compatible dual 4:1 multiplexer/demultiplexer. The VS3V2253
contains two mux/demux channels with common path control (S0 & S1) and individual active LOW enables
/E
A
and /E
B
. The low ON resistance of VS3V253 allows inputs to be connected to outputs without adding
propagation delay and without generating additional signal noise. The VS3V2253 has 25
resistors in series
with the switches to reduce ground-bounce noise and signal reflections.
The VS3V253 and VS3V2253 mux/demux switches are designed for 3.3V to 2.5V, or 2.5V to 1.8V
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 VS3V253 and VS3V2253 ideal interface elements for hot-swapping
applications.
