The MAX4684/MAX4685 low on-resistance (RON), lowvoltage, dual single-pole/double-throw (SPDT) analog
switches operate from a single +1.8V to +5.5V supply.
The MAX4684 features a 0.5Ω (max) RON for its NC
switch and a 0.8Ω (max) RON for its NO switch at a
+2.7V supply. The MAX4685 features a 0.8Ω max onresistance for both NO and NC switches at a +2.7V
supply.
Both parts feature break-before-make switching action
(2ns) with tON = 50ns and tOFF = 40ns at +3V. The digital logic inputs are 1.8V logic-compatible with a +2.7V to
+3.3V supply.
The MAX4684/MAX4685 are packaged in the chipscale
package (UCSP)™, significantly reducing the required
PC board area. The chip occupies only a 2.0mm ✕
1.50mm area. The 4 ✕ 3 array of solder bumps are
spaced with a 0.5mm bump pitch.

Note 1: Signals on NO_, NC_, and COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device
can be exposed to during board level solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection reflow. Preheating is required. Hand or wave soldering is not allowed.
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.

The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive
value a maximum.
Note 4: Guaranteed by design.
Note 5: ΔRON = RON(MAX) - RON(MIN), between NC1 and NC2 or between NO1 and NO2.
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 7: Leakage parameters are 100% tested at TA = +85°C, and guaranteed by correlation over rated temperature range.
Note 8: Off-isolation = 20log10 (VCOM / VNO), VCOM = output, VNO = input to off switch.
Note 9: UCSP and TDFN parts are 100% tested at +25°C only and guaranteed by design and correlation at the full hot-rated
temperature.
Note 10: -40°C specifications are guaranteed by design.

Analog Switch—Normally Open Terminal
Detailed Description
The MAX4684/MAX4685 are low on-resistance, lowvoltage, dual SPDT analog switches that operate from a
+1.8V to +5.5V supply. The devices are fully specified
for nominal 3V applications. The MAX4684/MAX4685
have break-before-make switching and fast switching
speeds (tON = 50ns max, tOFF = 40ns max).
The MAX4684 offers asymmetrical normally closed
(NC) and normally open (NO) RON for applications that
require asymmetrical loads (examples include speaker
headsets and internal speakers). The part features a
0.5Ω max RON for its NC switch and a 0.8Ω max RON
for its NO switch at the 2.7V supply. The MAX4685 features a 0.8Ω max on-resistance for both NO and NC
switches at the +2.7V supply.
Applications Information
Digital Control Inputs
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings
may cause permanent damage to devices.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog 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 <20mA, add
a small signal diode (D1) as shown in Figure 1. Adding
a protection diode reduces the analog range to a diode
drop (about 0.7V) below V+ (for D1). RON increases
slightly at low supply voltages. Maximum supply voltage (V+) must not exceed +6V. Protection diode D1
also protects against some overvoltage situations. No
damage will result on Figure 1’s circuit if the supply
voltage is below the absolute maximum rating applied
to an analog signal pin.
The MAX4684/MAX4685 logic inputs accept up to
+5.5V regardless of supply voltage. For example, with a
+3.3V supply, IN_ may be driven low to GND and high
to 5.5V. Driving IN_ rail-to-rail minimizes power consumption. Logic levels for a +1.8V supply are 0.5V (low)
and 1.4V (high).

Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) are passed with very little change in onresistance (see Typical Operating Characteristics). The
switches are bidirectional, so the NO_, NC_, and COM_
pins can be either inputs or outputs.

UCSP Reliability
The chip-scale package (UCSP) represents a unique
packaging form factor that may not perform equally to a
packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the
user’s assembly methods, circuit board material, and
usage environment. The user should closely review
these areas when considering use of a UCSP package.
Performance through Operating Life Test and Moisture
Resistance remains uncompromised as it is primarily
determined by the wafer-fabrication process.
Mechanical stress performance is a greater consideration for a UCSP package. UCSPs are attached through
direct solder contact to the user’s PC board, foregoing
the inherent stress relief of a packaged product lead
frame. Solder joint contact integrity must be considered. Information on Maxim’s qualification plan, test
data, and recommendations are detailed in the UCSP
application note, which can be found on Maxim’s website at www.maxim-ic.com.

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.
