Bar graph arrays are light emitting diodes (LEDs) that are used for solid state metering in applications such as audio monitoring, telecommunications, and instrumentation

Photodiodes are used for the detection of optical power (UV, Visible, and IR) and for the conversion of optical power to electrical power.

Diode arrays are composed of multiple discrete (usually unconnected) diodes on a single silicon chip.

Focal plane arrays (FPA) are detectors consisting of a linear or two-dimensional matrix of individual detector elements, typically used at the focus of an imaging system

Antennas are structures or devices used to collect or radiate electromagnetic waves.

RAID disk arrays are collections of storage disks with integrated controllers to manage the storage of data.

Field-programmable gate arrays (FPGAs) have a different architecture than SPLDs and CPLDs, and typically offer higher capacities.
