General Description
The MAX4754/MAX4755/MAX4756 low on-resistance,
analog switches operate from a single +1.8V to +5.5V
supply. The MAX4754 and MAX4755 are dual, double-
pole, double-throw (DPDT) switches. The MAX4756 is a
quad, single-pole double-throw (SPDT) switch. They
are configured to route either audio or data signals.
The MAX4754 has four 0.5
SPDT switches for audio-
signal routing and two logic control inputs. The
MAX4755 has four 0.5
SPDT switches (with two
switches that have an additional 11
series resistor at
the NC terminals). This allows users to drive an 8
speaker as a 32
load (ear speaker). The MAX4756
has four 0.5
SPDT switches controlled by one logic
control input and an enable pin (EN) to disable the
switches.
The MAX4754/MAX4755/MAX4756 are available in a
space-saving 16-pin thin QFN and a tiny 16-bump 2mm
x 2mm chip-scale package (UCSPTM).

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 in this data sheet; the most negative value is shown in the minimum column.
Note 3:
UCSP parts are 100% tested at +25C and limits across the full temperature range are guaranteed by correlation and
design. Thin QFN parts are 100% tested at +85C and limits across the full temperature range are guaranteed by correla-

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
