DESCRIPTION
The IL215AT/216AT/217AT is an optically coupled
pair 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 electrical
isolation between input and output. The IL215AT/
216AT/217AT 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-
holes 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.
