Detailed Description
The MAX4674 is a low on-resistance (RON), low-volt-
age, quad 2:1 analog multiplexer/demultiplexer that
operates from a +1.8V to +5.5V single supply. The
MAX4674 features very fast switching speed (tON =
18ns max, tOFF = 6ns max) and guaranteed break-
before-make switching. Its low RON allows high continu-
ous currents to be switched in a variety of applications.
Digital Interface
A0 and EN are CMOS digital inputs that meet TTL logic
levels when V+ = 5V. Note that A0 and EN can exceed
the voltage at V+ to a maximum of +5.5V. This feature
allows operation of the MAX4674 from a +3.3V supply
while controlling it with 5V CMOS logic signals.
The Pin Configuration/Functional Diagram/Truth Table
located on the first page of this data sheet details the
operation of the MAX4674.
Applications Information
Power-Supply Considerations
Overview
The MAX4674 construction is typical of most CMOS
analog switches. It has two supply pins, V+ and GND,
used to drive the internal CMOS switches and set the
limits of the analog voltage on any switches. Reverse
ESD-protection diodes are internally connected
between each analog-signal pin and both V+ and
GND. If any analog signal exceeds V+ and GND, one
of these diodes conducts. During normal operation,
these and other reverse-biased ESD diodes leak, form-
ing the only current drawn from VCC or GND.
Virtually all the analog leakage current comes from the
ESD diodes. Although the ESD diodes on a given sig-
nal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by
either V+ or GND and the analog signal. This means
