MAXIM MAX4717, MAX4718 Technical data

General Description
The MAX4717/MAX4718 low-voltage, low on-resistance (RON), 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 RON(max) SPDT switches with 1.2Ω flatness and 0.3Ω matching between channels. The MAX4718 features one 4.5Ω RON(max) SPDT switch and one 20Ω RON(max) SPDT switch. The 20Ω switch has a guaranteed matching and flatness of
0.4Ω and 1.2Ω, respectively. These switches offer break­before-make switching (1ns) with tON<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.
Applications

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.
