Manufacturer
Maxim
Datasheet
The MAX4854H/MAX4854HL analog switches operate
from a single +2V to +5.5V supply and can handle sig-
nals greater than the supply rail. These devices feature
four low on-resistance (7Ω) single-pole/single-throw
(SPST) switches, with 27.5pF on-capacitance, making
them ideal for data signals. If the input signal exceeds the
supply rail, the switches become high impedance and
prevent the signal from feeding through to the output.
The MAX4854H/MAX4854HL are available in the
space-saving (3mm x 3mm), 16-pin, thin QFN package
and operate over the extended (-40°C to +85°C) tem-
perature range.
