Fast, Low-Voltage, Dual 4 SPDT  
CMOS Analog Switches  
General Description  
Features  
The MAX4635/MAX4636 are fast, dual 4 single-  
pole/double-throw (SPDT) analog switches that operate  
with supply voltages from +1.8V to +5.5V. High switch-  
ing speeds, 1 on-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.

Note 1: Signals on NO_, NC_, or COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maxi-  
mum current rating.  
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.

Logic Inputs  
Detailed Description  
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.  
The MAX4635/MAX4636 are low-on-resistance (R ),  
ON  
low-voltage, dual SPDT analog switches that operate  
from a +1.8V to +5.5V supply. The MAX4635/MAX4636  
feature very fast switching speed (t  
= 14ns max,  
ON  
t
= 6ns max) and guaranteed break-before-make  
OFF  
switching. The low maximum R  
allows high continu-  
ON  
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.  
ous currents to be switched in a variety of applications.  
Applications Information  
Power-Supply Sequencing and  
Overvoltage Protection  
V+  
10nF  
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).

MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.  
OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NO_ OR NC_ TERMINAL ON EACH SWITCH.  
ON-LOSS IS MEASURED BETWEEN COM_ AND "ON" NO_ OR NC_ TERMINAL ON EACH SWITCH.  
CROSSTALK IS MEASURED FROM ONE CHANNEL TO ALL OTHER CHANNELS.  
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.

Figure 5. Overvoltage Protection Using Two External Blocking  
Diodes  
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.
