General Description
The MAX4715/MAX4716 are low on-resistance, lowvoltage, single-pole/single-throw (SPST) analog switches that operate from a +1.6V to +3.6V single supply.
The MAX4715 is normally open (NO), and the MAX4716
is normally closed (NC). These devices also have fast
switching speeds (tON= 18ns max, t
OFF
= 12ns max).
When powered from a +3V supply, the MAX4715/
MAX4716 offer 0.4Ω max on-resistance (RON) with 0.1Ω
max RONflatness. Their digital logic inputs are +1.8V
CMOS compatible when using a single +3V supply.
The MAX4715 is pin compatible with the MAX4594, and
the MAX4716 is pin compatible with the MAX4595. The
MAX4715/MAX4716 are available in SC70-5 packages.

Detailed Description
The MAX4715/MAX4716 are low on-resistance (RON),
low-voltage, single-pole/single-throw (SPST) analog
switches that operate from a +1.6V to +3.6V single supply. The MAX4715 is normally open (NO), and the
MAX4716 is normally closed (NC).
When powered from a +3V supply, their 0.4Ω R
ON
allows high continuous currents to be switched in a
variety of applications.
Applications Information
Logic Inputs
The MAX4715/MAX4716 logic inputs 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
consumption.
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.
