DESCRIPTION
The IL215AT/IL216AT/IL217AT are optically coupled
pairs with a Gallium Arsenide infrared LED and a sili-
con NPN phototransistor. Signal information, including
a DC level, can be transmitted by the device while
maintaining a high degree of electrical isolation
between input and output. The IL215AT/IL216AT/
IL217AT comes in a standard SOIC-8 small outline
package for surface mounting which makes it ideally
suited for high density applications with limited space.
In addition to eliminating through hole requirements,
this package conforms to standards for surface
mounted devices.
The high CTR at low input current is designed for low
power consumption requirements such as CMOS
microprocessor interfaces.
