MAX4704EUB
Low-Voltage, 60ヘ,4:1 Analog Multiplexer in QFN
General DescriptionThe MAX4704 low-voltage, 4-channel analog multiplex-
er operates from a single +1.8V to +5.5V supply. The
MAX4704 features break-before-make switching action
with a tON= 60ns and tOFF= 20ns at +3V.
When powered from a +2.7V supply, the device has a
60Ω(max) on-resistance (RON), with 3Ω(max) RON
matching and 5Ωmax RONflatness. The digital logic
inputs are 1.8V-logic compatible from a +2.7V to +3.3V
supply. The MAX4704 is available in both a space-sav-
ing 12-pin QFN (3mm x 3mm) package and a 10-pin
µMAX package.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS—Single +3V Supply(V+ = +2.7V to +3.3V, VIH= +1.4V, VIL= +0.5V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at V+ = +3V and = +25°C.) (Notes 2, 3)
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 1:Signals on INH, ADD_, NO_, and COM exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current
to maximum current rating.

Note 2:The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3:-40°C specifications are guaranteed by design.
Note 4:∆RON= RON(MAX)- RON(MIN).
Note 5:Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 6:Leakage currents are 100% tested at TA= +85°C. Limits across the full temperature range are guaranteed by correlation.
Note 7:Guaranteed by design.
Note 8:Off-Isolation = 20log10(VCOM/ VNO_), VCOM= output, VNO_= input to off switch.
Note 9:Between any two switches.
