Description
Each channel contains a light emitting diode which is optically coupled to an integrated high gain
photon detector. The high gain output stage features an open collector output providing both lower
saturation voltage and higher signalling speed than a conventional Photo-Darlington optocoupler.
The supply voltage can be operated as low as 2.0V without adversely affecting the parametric
performance. The High Current Transfer Ratio of the optocouplers makes them ideal for low input
current, min 0.5mA, applications.
The radiation immunity of the optocouplers compared to conventional photo transistor optocouplers
is due to the shallow depth and small junctions offered by the IC process.
The optocoupler family is also available in various package styles including 6, 8 and 16 pin DIP
through hole, 16 pin surface mount DIP flat pack and a 6 Pin leadless ceramic chip carrier. The
devices can be purchased with lead bend and plating options.
ISOCOM optocouplers are offered on the basis of similarity of emitter and detector therefore the
performance characterization is identical, subject to the limitations of the packages. The wafer die
similarities apply to the optocouplers for high reliability screening and radiation testing.
