General Description
The MAX4696/MAX4697/MAX4698 low on-resistance
(R
ON
), low-voltage analog switches operate from a sin-
gle +2.0V to +5.5V supply. The MAX4696/MAX4697 are
single-pole/single-throw (SPST) analog switches, and
the MAX4698 is a single-pole/double-throw (SPDT) ana-
log switch. The MAX4696 is a normally open (NO)
switch, and the MAX4697 is a normally closed (NC)
switch.
When powered from a 2.7V supply, these devices feature
35
(max) R
ON
, with 2
(max) R
ON
matching and 13
(max) flatness. The MAX4696/MAX4697/MAX4698 offer
fast switching speeds (t
ON
= 80ns max, t
OFF
= 25ns
max). The MAX4698 offers a break-before-make function.
The digital logic inputs are 1.8V logic compatible from a
+2.7V to +3.3V supply and are TTL/CMOS compatible
from a +4.5V to +5.5V supply. The MAX4696/MAX4697/
MAX4698 are packaged in the chip-scale package
(UCSPTM), significantly reducing the required PC board
area. The device occupies only a 1.50mm
1.02mm
area. The 3
2 array of solder bumps are spaced with
a 0.5mm bump pitch.

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.
