VS3V253 / VS3V2253
High-speed 3.3V CMOS VSwitch
Dual 4:1 Mux/Demux
Applications
= 3.3V to 2.5V translation
= 2.5V to 1.8V translation
= Hot-Swapping
= Logic replacement
= Memory bank, video, and audio
switching
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
/EA and /EB. 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 25resistors 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.
Features
= Enhanced N-FET with no DC path to VCC
or GND in normal operating signal voltage
range.
= Low impedance switches connect inputs to
outputs with near-zero propagation delay:
5(VS3V253) and 25(VS3V2253)
= Pin-compatible with 74LVC253 or
equivalent logic devices
= Zero added ground bounce or signal noise
= Break-before-make feature
= Undershoot clamp diodes on all switch and
control pins
= ESD rating >2000V (Human Body Model)
or >200V (Machine Model)
= Latch-up current >100mA
= Available in 150-mil wide QSOP package

Notes:
1. RON is measured by forcing specified current into the ‘output’ node of the switch with the ‘input’ node of the switch
at the specified voltage.
2. Typical value is specified at VCC = 3.3V and TA = 25oC.
3. Typical value is specified at VCC = 2.5V and TA = 25o

Notes:
1. For conditions shown as Min or Max, use the appropriate values per Recommended Operating Conditions.
2. Per control input. All other control inputs at GND. Switch I/O pins do not contribute to ICC.
3. This parameter represents the average DC current resulting from the switching of internal nodes of the device at a
given frequency. The switch I/O pins make insignificant contribution to the dynamic power supply current of the
device. This parameter is guaranteed, but not production tested.
