MAX4717EUB+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
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 4.5Ω R
ON
(max) SPDT
switches with 1.2Ω flatness and 0.3Ω matching between
channels. The MAX4718 features one 4.5Ω R
ON
(max)
SPDT switch and one 20Ω R
ON
(max) SPDT switch. The
20Ω switch has a guaranteed matching and flatness of
0.4Ω and 1.2Ω, 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
(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.
These switches are also available in 10-pin µMAX
®
and
10-pin TDFN packages.

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.
