Triple DPDT, Low-Capacitance Data Switches
General Description
The MAX4996/MAX4996L triple DPDT analog switches
operate from a single +2.5V to +5.5V supply, and fea-
ture 2.0Ω (typ) on-resistance, low 6pF (typ) on-capaci-
tance, and low power-supply current consumption. The
MAX4996/MAX4996L combine the low capacitance and
low resistance necessary for high-frequency switching
applications in portable electronics.
The MAX4996/MAX4996L have three logic inputs to
control the switches in pairs. The MAX4996 has an
active-high enable input (EN) to disable the switches,
while the MAX4996L has an active-low enable input
(EN) to disable the switches. The enable input decreas-
es the supply current and also places the COM_ out-
puts in a high-impedance state.
The MAX4996/MAX4996L feature a 5µA (max) supply-
current consumption when the logic inputs are not
rail-to-rail. This feature is especially valuable in applica-
tions where direct interface to low-voltage processors
is necessary.
The MAX4996/MAX4996L are available in a space-
saving 24-pin (3.5mm x 3.5mm) TQFN package and
operate over the -40°C to +85°C temperature range.

Note 1:
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations see
www.maxim-ic.com/thermal-tutorial.
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.
