MAXIM MAX4854H, MAX4854HL Technical data

General Description

The MAX4854H/MAX4854HL analog switches operate
from a single +2V to +5.5V supply and can handle sig­nals 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) tem­perature range.

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
