19-3472; Rev 0; 10/04
7Ω Quad SPST Switches
with Over-Rail Signal Handling
General Description
The MAX4854 quad single-pole/single-throw (SPST)
switch operates from a single +2V to +5.5V supply and
can handle signals greater than the supply rail. This
switch features low 7Ω on-resistance with 30pF on-
capacitance, making it ideal for switching data signals.
For over-rail applications, this device passes signals
greater than the positive supply (up to +5.5V) through
the switch without distortion.
The MAX4854 is available in the space-saving, 16-pin,
3mm x 3mm thin QFN package and operates over the
-40°C to +85°C extended temperature range.
