DESCRIPTION
The ILD256 is a dual channel optocoupler. Each
channel consists of two infrared emitters con-
nected in anti-parallel and coupled to a silicon
NPN phototransistor detector.
These circuit elements are constructed with a stan-
dard SOIC-8 footprint.
The product is well suited for telecom applications
such as ring detection or off/on hook status, given
its bidirectional LED input and guaranteed current
transfer ratio (CTR) of 20% at I_F= 10 mA.
