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 µTDFN package, alleviating
board space limitations.
