MAXIM MAX4699ETE+

19-2129; Rev 2; 10/09
Low-Voltage, Dual DPDT/Quad SPDT
Analog Switches in QFN
The MAX4699/MAX4701/MAX4702 are low-voltage,
single-supply CMOS analog switches. The MAX4699/
MAX4701 are dual double-pole/double-throw (DPDT)
switches with two control inputs that control two
single-pole/double-throw (SPDT) switches each. The
MAX4702 is a quad SPDT switch with one control input
and one low-voltage digital logic power supply.
These devices operate from a single +1.8V to +5.5V
power supply. When powered from a +2.7V supply the
MAX4699/MAX4701/MAX4702 offer a 75Ω on-resistance (RON), with 12Ω max RON flatness and 4Ω max
matching between channels. Each switch has rail-to-rail
signal handling, fast switching speeds of tON = 35ns,
tOFF = 20ns, and a maximum 1nA of leakage current.
The MAX4699/MAX4701 digital inputs are 1.8V-logic
compatible when operated from a +3V supply. The
MAX4702’s digital inputs feature a 1.0V threshold when
powered with a 1.5V logic supply.
The MAX4699 is available in a space-saving 16-lead
4mm x 4mm TQFN package. The MAX4701/MAX4702
are available in space-saving 16-lead 3mm x 3mm TQFN
16-pin TSSOP packages.

maximum 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.

Detailed Description
The MAX4699/MAX4701 are low-voltage CMOS analog
switches that operate from a single +1.8V to +5.5V
power supply. The MAX4702 requires an additional
logic supply that allows for setting lower logic thresholds. The MAX4699/MAX4701 are double-pole/doublethrow (DPDT) devices. The MAX4702 is a quad
single-pole/double-throw (SPDT) device. These devices
feature a break-before-make switching, fast switching
speeds (with V+ = 5V: tON = 18ns max, tOFF = 9ns max
and with V+ = 3V: tON = 35ns, tOFF = 20) and rail-to-rail
signal handling. A logic input on the MAX4702 allows
for logic thresholds as low as 1.0V.

Applications Information
Analog Signal Levels
Figure 1. Overvoltage Protection Using Two External Blocking
Diodes
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in onresistance (see Typical Operating Characteristics). The
switches are bidirectional, so the NO, NC, and COM pins
can be used as either inputs or outputs.

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 the 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. 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. TTL compatibility is not
guaranteed when D2 is added.
Protection diodes D1 and D2 also protect against some
overvoltage situations. With Figure 1’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 will result.
VL Logic Input (MAX4702)
The MAX4702 features a VL logic input that allows for
lower logic input thresholds down to 1.0V min for VIH in
the quad SPDT configuration. Power-up VL after V+ has
been powered with a minimum of 1.5V to ensure proper
operation of the device.

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.
