+1.8V to +5.5V, 2.5Ω, Single SPST Analog Switches
ISL54504, ISL54505
The Intersil ISL54504 and ISL54505 devices are low
ON-resistance, low voltage, bidirectional, single
pole/single throw (SPST) analog switches designed to
operate from a single +1.8V to +5.5V supply. Targeted
applications include battery powered equipment that
benefit from low r_ON resistance (2.5Ω), excellent r_ON
flatness (0.6Ω), and fast switching speeds (t_ON = 25ns,
t_OFF = 15ns). The digital logic input is 1.8V CMOS
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 family of parts may
be used to switch in additional functionality while
reducing ASIC design risk. The ISL54504 and ISL54505
are offered in a 6 Ld 1.2mmx1.0mmx0.4mm pitch
µTDFN package and a 6 Ld SOT-23 package, alleviating
board space limitations.
The ISL54504 has one normally open (NO) switch and
ISL54505 has one normally closed (NC) switch.
