Hex SPDT Data Switch
MAX4947/MAX4948
Hex SPDT Data Switch
EVALUATION KIT AVAILABLE
General Description
The MAX4947/MAX4948 analog switches operate from a
single +1.8V to +5.5V supply. These switches feature a
low 30pF (typ) capacitance for high-speed data switch-
ing applications.
The MAX4947 is a triple double-pole/double-throw (DPDT)
switch, and the MAX4748 is a hex single-pole/double-
throw (SPDT) switch with one control logic input.The
MAX4947 has three logic inputs to control the switches in
pairs. The MAX4948 has one logic input and an enable
input (EN) to disable the switches.
The MAX4947/MAX4948 are available in small 24-pin
(4mm x 4mm) TQFN and 25-bump (2.5mm x 2.5mm)
chip-scale packages (UCSP™).

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.

Note 2:The algebraic convention is used. The most negative value is shown in the minimum column.
Note 3:UCSP parts are 100% tested at TA= +25°C. Limits across the full temperature range are guaranteed by correlation and
design. TQFN parts are guaranteed by correlation and design at TA= --40°C.
Note 4:RON andΔRON matching specifications are guaranteed by design.
Note 5:ΔRON = RON(MAX)- RON(MIN).
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:Guaranteed by design, not production tested.
Note 8:Off-Isolation = 20log10[VCOM_/ (VNO_ or VNC_)], VCOM_= output, VNO_or VNC_= input to off switch.
