ISL84684II
FN6190.0
Ultra Low ON-Resistance, Low Voltage,
Single Supply, Dual SPDT Analog Switch
in Chipscale Package
The Intersil ISL84684II device is a low ON-resistance, low
voltage, bidirectional, dual single-pole/double-throw (SPDT)
analog switch designed to operate from a single +1.8V to
+4.5V supply. Targeted applications include battery powered
equipment that benefit from low RON (0.21Ω) and fast
switching speeds (tON = 43ns, tOFF = 27ns). The digital logic
input is 1.8V logic-compatible when using a single +1.8V to
4.5V supply.
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This part may be used to “mux-in”
additional functionality while reducing ASIC design risk. The
ISL84684II is offered in a 2.00mm x 1.50mm chipscale
package, alleviating board space limitations. The 4x3 array of
solder balls are spaced with a 0.5mm ball pitch.
The ISL84684II is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally closed (NC) switches. This configuration can be

used as a dual 2-to-1 multiplexer. The ISL84684II is pin
compatible with the MAX4684 and MAX4685.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Signals on NC, NO, IN, or COM exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to maximum current ratings.
3. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
4. Permitted soldier profiles are limited to only those recommended in the industry standard specification, JEDEC J-STD-020. Preheating is
required. Hand or wave soldering is not allowed. See Technical Brief TB451.
