Photologic(R) Optically Coupled Isolator OPI125, OPI126, OPI127, OPI127-032, OPI128 Features: * Four output options * 15 kV input-to-output isolation * * * * voltage * Direct TTL/STTL interface * High noise immunity Data rates to 250 KBit/s Hermetically sealed TX-TXV process available UL File No. E 58730* Product Photo Here 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(R) 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.
