Maxim MAX4754EBE-T 0.5-ohm, quad spdt switches in ucsp/qfn Datasheet

19-2942; Rev 0; 8/03
0.5Ω, Quad SPDT Switches in UCSP/QFN
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, doublepole, 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 0.5Ω SPDT switches for audiosignal routing and two logic control inputs. The
MAX4755 has four 0.5Ω SPDT switches (with two
switches that have an additional 11Ω series resistor at
the NC terminals). This allows users to drive an 8Ω
speaker as a 32Ω load (ear speaker). The MAX4756
has four 0.5Ω SPDT switches controlled by one logic
control input and an enable pin (EN) to disable the
switches.

Note 1: Signals on NO_, NC_, COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to 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.

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 +25°C and limits across the full temperature range are guaranteed by correlation and
design. Thin QFN parts are 100% tested at +85°C and limits across the full temperature range are guaranteed by correlation and design.
Note 4: RON and ∆RON matching specifications are guaranteed by design.
Note 5: ∆RON = 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.
Note 9: Between any two switches.

MAX4754/MAX4755/MAX4756
Pin Description
MAX4754/MAX4755/MAX4756
0.5Ω, Quad SPDT Switches in UCSP/QFN
Detailed Description
The MAX4754/MAX4755/MAX4756 low on-resistance
analog switches operate from a single +1.8V to +5.5V
supply. The devices are fully specified for nominal 3V
applications.
The MAX4754 DPDT switch has two logic control inputs
with each input controlling two SPDT switches. Each
switch has a 0.5Ω on-resistance in the NO and NC terminals making it ideal for switching audio signals.
The MAX4755 DPDT switch also has four 0.5Ω SPDT
switches with the switch pairs 1 and 2 adding an 11.5Ω
series resistor to the NC terminal. This feature allows
the user to drive an 8Ω speaker as a 32Ω load, allowing
it to be used as an ear speaker. Two logic control
inputs are used to control the four switches.
The MAX4756 has four 0.5Ω SPDT switches controlled
by one logic control input (INA) and EN input to disable
the switches.
Applications Information
Analog Signal Levels
Analog signal inputs over the full voltage range (0V to
V+) are passed through the switch with minimal change
in on-resistance (see the Typical Operating Characteristics). The switches are bidirectional so NO_, NC_,
and COM_ can be either inputs or outputs.
Power-Supply Bypassing
Power-supply bypassing improves noise margin and prevents switching noise from propagating from the V+ supply to other components. A 0.1µF capacitor connected
from V+ to GND is adequate for most applications.
UCSP Applications Information
For the latest application details on UCSP construction,
dimensions, tape carrier information, printed circuit
board techniques, bump-pad layout, and recommended reflow temperature profile, as well as the latest information on reliability testing results, go to the Maxim
website at www.maxim-ic.com/ucsp for the Application
Note: UCSP—A Wafer-Level Chip-Scale Package.
Digital Control Inputs
The MAX4754/MAX4755/MAX4756 logic inputs accept
up to +5.5V regardless of the supply voltage. For
example, with a +3.3V supply IN_ can be driven low to
GND and high to +5.5V, which allows mixed logic levels in a system. Driving the control logic inputs rail-torail also minimizes power consumption. For a +3V
supply voltage, the logic thresholds are 0.5V (low) and
1.4V (high).
For the MAX4756, drive EN low to enable the COM_.
When EN is high, COM _ is high impedance.

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 THE OTHER CHANNEL.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
