DESCRIPTION
The ILH100 is designed especially for hi-rel applica-
tions requiring optical isolation with high current
transfer ratio and low saturation VCE. Each opto-
coupler consists of a light emitting diode and a NPN
silicon phototransistor mounted and coupled in an 8
pin hermetically sealed DIP package. The ILH100's
low input current makes it well suited for direct
CMOS to LSTTL/TTL interfaces.
