Description:
Each OPI125, OPI126, OPI127, OPI127-032 and OPI128 consists of an optically coupled isolator with a gallium
arsenide infrared emitting diode coupled to a monolithic integrated circuit. This circuit incorporates a photodiode, a
linear amplifier and a Schmitt trigger on a single silicon chip. For maximum long-term stability, both the diode and
the Photologic® sensor are hermetically sealed in separate packages and then mounted in a high dielectric plastic
housing.
These devices feature TTL/LSTTL compatible logic level output that can drive up to 8 TTL loads directly without
additional circuitry. Also featured are medium-speed data rates to 250 KBit/s, with typical rise and fall times of 70
nanoseconds. *UL recognition is for 15KVDC to 100° C.
TX and TXV processing is available. For more information, contact your local representative or OPTEK.
Applications:
• High voltage isolation between
input and output
• Electrical isolation in dirty
environments
• Industrial equipment
• Medical equipment
• Office equipment
