Detailed Description
The MAX4714 is a low-on-resistance (R
ON
), low-volt-
age, single-pole/double-throw (SPDT) analog switch
that operates from a +1.6V to +3.6V supply. The
MAX4714 has break-before-make switching. This
device also has fast switching speeds (t
ON
= 18ns,
max, t
OFF
= 12ns, max).
When powered from a +3V supply, the 0.8Ω (max) R
ON
allows high continuous currents to be switched in a
variety of applications.
Applications Information
Logic Inputs
The MAX4714 logic input can be driven up to +3.6V
regardless of the supply voltage. For example, with a
+3.3V supply, IN may be driven low to GND and high to
+3.6V. Driving IN rail-to-rail minimizes power consump-
tion.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in
on-resistance (see Typical Operating Characteristics).
The switches are bidirectional, so the NO, NC, and
COM pins can be used as either inputs or outputs.
