Ω
, 300MHz Bandwidth, Dual SPDT Analog
Switch in UCSP
General Description
The MAX4719 low-voltage, low on-resistance (R
ON
),
dual single-pole/double throw (SPDT) analog switch
operates from a single +1.8V to +5.5V supply. The
MAX4719 features 20Ω R
ON
(max) with 1.2Ω flatness
and 0.4Ω matching between channels. The switch offers
break-before-make switching (1ns) with t
ON
<80ns and
t
OFF
<40ns at +2.7V. The digital logic inputs are +1.8V
logic compatible with a +2.7V to +3.6V supply.
The switch is packaged in a chip-scale package
(UCSP™), significantly reducing the required PC board
area. The chip occupies only a 2.0mm
✕
1.50mm area
and has a 4
✕
3 bump array with a bump pitch of
0.5mm. The MAX4719 is also available in a 10-pin
µMAX package.

Note 1:
Signals on COM_, NO_, or NC_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maxi-
mum current rating.
Note 2:
This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device
can be exposed to during board level solder attach and rework. This limit permits only the use of the solder profiles recom-
mended in the industry standard specification, JEDEC 020A, paragraph 7.6, table 3 for IR/VPR and convection reflow.
Preheating is required. Hand or wave soldering is not allowed.
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.

UCSP parts are 100% tested at +25°C only, and guaranteed by design over the specified temperature range. µMAX parts
are 100% tested at T
MAX
and guaranteed by design over the specified temperature range.
The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive
value is a maximum.
Guaranteed by design for UCSP parts.
∆R

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
