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.
