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 singlepole/
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 rON (0.29Ω) and fast switching speeds (tON = 40ns,
tOFF = 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.
