General Description
The MAX4717/MAX4718 low-voltage, low on-resistance
(R
ON
), dual single-pole/double throw (SPDT) analog
switches operate from a single +1.8V to +5.5V supply.
These devices are designed for USB 1.1 and audio
switching applications.
The MAX4717 features two 4.5
R
ON
(max) SPDT
switches with 1.2
flatness and 0.3 matching between
channels. The MAX4718 features one 4.5
R
ON
(max)
SPDT switch and one 20
R
ON
(max) SPDT switch. The
20
switch has a guaranteed matching and flatness of
0.4
and 1.2, respectively. These switches offer 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.
These switches are packaged in a chip-scale package
(UCSPTM), 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. These switches are also available in a 10-pin
MAX package.

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 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.
