General Description
The MAX4635/MAX4636 are fast, dual 4Ωsingle-
pole/double-throw (SPDT) analog switches that operate
with supply voltages from +1.8V to +5.5V. High switch-
ing speeds, 1Ωon-resistance flatness, and low power
consumption make these devices ideal for audio/video,
communications, and battery-operated devices.
Containing two independently controllable SPDT
switches in 10-pin µMAX and 10-pin 3mm x 3mm thin
QFN packages, the MAX4635/MAX4636 use little board
space, and have low power consumption ensuring min-
imal impact on your power budget. The analog signal
range extends to the supply rails. The MAX4635 has
inverted logic compared to the MAX4636.

Detailed Description
The MAX4635/MAX4636 are low-on-resistance (RON),
low-voltage, dual SPDT analog switches that operate
from a +1.8V to +5.5V supply. The MAX4635/MAX4636
feature very fast switching speed (tON = 14ns max,
tOFF = 6ns max) and guaranteed break-before-make
switching. The low maximum RON allows high continu-
ous currents to be switched in a variety of applications.
Applications Information
Logic Inputs
The MAX4635/MAX4636 logic inputs (IN1, IN2) can be
driven up to +5.5V, regardless of the voltage on V+.
This allows interfacing to 5V logic signals while operat-
ing with a +3.3V supply voltage without external level
translation.
Analog Signal Levels
Analog signals ranging 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 may be used as either inputs or outputs.
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum rat-
ings because stresses beyond the listed ratings can
cause permanent damage to the device. Proper
power-supply sequencing is recommended for all
CMOS devices. Always apply V+ before applying ana-
log signals, especially if the analog signal is not current
limited. If this sequencing is not possible, and if the
analog inputs are not current limited to less than 30mA,
add a small-signal diode (D1) as shown in Figure 5. If
the analog signal can dip below GND, add D2. Adding
protection diodes reduces the analog range to a diode
drop (about 0.7V) below V+ (for D1), and a diode drop
above ground (for D2).

On-resistance increases slightly at low supply voltages.
Maximum supply voltage (V+) must not exceed +6V.
Adding protection diode D2 causes the logic threshold
to be shifted relative to GND. Protection diodes D1 and
D2 also protect against some overvoltage situations.
With Figure 5’s circuit, if the supply voltage is below the
absolute maximum rating, and if a fault voltage up to
the absolute maximum rating is applied to an analog
signal pin, no damage results.
