DESCRIPTION
Emitter
The IL205A/206A/207A/208A are optically coupled
pairs with a Gallium Arsenide infrared LED and a
silicon NPN phototransistor. Signal information,
including a DC level, can be transmitted by the
device while maintaining a high degree of electri-
cal isolation between input and output. The IL205/
6/7/8 come in a standard SOIC-8 small outline
package for surface mounting which makes them
ideally suited for high density applications with lim-
ited space. In addition to eliminating through-holes
requirements, this package conforms to standards
for surface mounted devices.
