Low-Voltage, Single Supply, Dual SPST,

SPDT Analog Switches

Features

• Drop-in Replacements for MAX4541 - MAX4544,

DG9461, DG9262 - DG9263

The Intersil ISL84541–ISL84544 devices are precision, dual

analog switches designed to operate from a single +2.7V to

+12V supply. Targeted applications include battery powered

equipment that benefit from the devices’ low power

• Pin Compatible with MAX323 - MAX325

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 family of parts may be used to “mux-in”

additional functionality while reducing ASIC design risk. Some

of the smallest packages are available alleviating board space

limitations, and making Intersil’s newest line of low-voltage

switches an ideal solution.

The ISL84541/ISL84542/ISL84543 are dual single-

pole/single-throw (SPST) devices. The ISL84541 has two

normally open (NO) switches; the ISL84542 has two normally

closed (NC) switches; the ISL84543 has one NO and one NC

switch and can be used as an SPDT. The ISL84544 is a

committed SPDT, which is perfect for use in 2-to-1 multiplexer

applications.

• Guaranteed Break-Before-Make (ISL84543/ISL84544

only)

• Minimum 2000V ESD Protection per Method 3015.7

• TTL, CMOS Compatible

• Available in SOT-23 Packaging

Table 1 summarizes the performance of this family. For higher

performance, pin compatible versions, see the ISL43120 - 22

and ISL43210 datasheet.
