IL256AT
Vishay Semiconductors
DESCRIPTION
The IL256AT is an AC input phototransistor optocoupler. The
device consists of two infrared emitters connected in reverse
parallel and coupled to a silicon NPN phototransistor
detector.
These circuit elements are constructed with a standard
SOIC-8 foot print.
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)
minimum of 20 % at IF = 10 mA.
FEATURES
Guaranteed CTR symmetry, 2:1 maximum
