General Description

The MAX4717/MAX4718 low-voltage, low on-resistance

), 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

(max) SPDT

switches with 1.2Ω flatness and 0.3Ω matching between

channels. The MAX4718 features one 4.5Ω R

(max)

SPDT switch and one 20Ω R

(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

<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.
