optoisolator

optoisolator

[¦äp·tō′ī·sə‚lād·ər]
(electronics)
A coupling device in which a light-emitting diode, energized by the input signal, is optically coupled to a photodetector such as a light-sensitive output diode, transistor, or silicon controlled rectifier. Also known as optical coupler; optical isolator; optically coupled isolator; optocoupler; optoelectronic isolator; photocoupler; photoisolator.

optoisolator

A device that transfers a signal optically between two electronic circuits, isolating them from each other. An electronic signal on one side is converted to light by a visible or infrared LED. The receiver on the other side detects the light signal and converts it back into electronic format. Optoisolators are used to protect circuits against damage from current surges.

The device is housed in a SDIP package which occupies half the space of the standard 8-pin DIP devices, and it is believed to be the smallest optoisolator package currently available that is designed to comply with reinforced insulation class international safety standards.
The Company's portfolio includes amplifiers, attenuators, battery chargers, circulators, DC/DC converters, demodulators, detectors, diodes, directional couplers, front-end modules, hybrids, infrastructure RF subsystems, isolators, LED drivers, mixers, modulators, optocouplers, optoisolators, phase shifters, PLLs/synthesizers/VCOs, power dividers/combiners, power management devices, receivers, switches, technical ceramics and voltage regulators.
Despite the low power consumption, these digital optoisolators have very low pulse width distortion, which is the time difference between the received high voltage pulse and the transmitted digital signal level pulse.

The company's patented microinverter architecture enables increased reliability by eliminating the most failure prone components, like electrolytic capacitors and optoisolators, which are used in central inverters and competitive microinverters.
Pull-up resistors are provided for all pins so that they may be connected directly to optoisolators and contacts.
