DESCRIPTION
The ILD610 Series is a dual channel optocoupler
series for high density applications. Each channel
consists of an optically coupled pair with a Gallium
Arsenide infrared LED and a silicon NPN pho-
totransistor. Signal information, including a DC
level, can be transmitted by the device while main-
taining a high degree of electrical isolation between
input and output. The ILD610 Series is the dual ver-
sion of SFH610 Series and uses a repetitive pin-out
configuration instead of the more common alternat-
ing pin-out used in most dual couplers.
