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.
