Ultra Low ON-Resistance, +1.65V to +4.5V,
Single Supply, Dual SPST Analog Switch
The Intersil ISL54048 and ISL54049 devices are low ON-
resistance, low voltage, bidirectional, dual single-pole/single-
throw (SPST) analog switches designed to operate from a
single +1.65V to +4.5V supply. Targeted applications include
battery powered equipment that benefit from low r_ON (0.29Ω)
and fast switching speeds (t_ON = 40ns, t_OFF = 20ns). The
digital logic input is 1.8V logic-compatible when using a single
+3V 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
ISL54048 and ISL54049 are offered in a small form factor
package, alleviating board space limitations.
The ISL54048 has two normally open (NO) SPST switches
and the ISL54049 has two normally closed (NC) SPST
switches.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
