FN6128.0

Ultra Low ON-Resistance, +1.65V to +4.5V,

Single Supply, Dual SPDT Analog Switch

The Intersil ISL8484 device is a low ON-resistance, low

voltage, bidirectional, dual single-pole/double-throw (SPDT)

analog switch designed to operate from a single +1.65V to

+4.5V supply. Targeted applications include battery powered

Features

• Pb-Free Available as an Option (RoHS Compliant)

(see Ordering Info)

• Pin Compatible Replacement for the MAX4684 and

MAX4685

input is 1.8V logic-compatible when using a single +3V supply.

With a supply voltage of 4.2V and logic high voltage of 2.85V

at both logic inputs, the part draws only 10µA max of I+

current.

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

ISL8484 is offered in small form factor packages, alleviating

board space limitations.

• Guaranteed Break-before-Make

The ISL8484 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 ISL8484 is pin

compatible with the MAX4684 and MAX4685.

• 1.8V Logic Compatible (+3V supply)

• Low I+ Current when VinH is not at the V+ Rail

• Available in 10 lead 3x3 Thin DFN and 10 lead MSOP
