, Single SPST Analog
Switches
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 (2.5惟), excellent r
ON
flatness (0.6惟), 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 ISL54054, ISL54055 are offered in a 6 Ld
1.2mmx1.0mmx0.4mm pitch 碌TDFN package, alleviating
board space limitations.
The ISL54504 has one normally open (NO) switch and
ISL54505 has one normally closed (NC) switch.
