The Toshiba TLP174GA consists of an aluminum gallium arsenide
infrared emitting diode optically coupled to a photo-MOSFET in a SOP,
which is suitable for surface mount assembly.
The TLP174GA is suitable for the modem applications which require
space savings.
4-pin SOP (2.54SOP4): Height = 2.1 mm, Pitch = 2.54 mm
