OPI128 Datasheet | TT Electronics

Features : - Multiple output options - 15 k V dc 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- Description : Each OPI125, OPI126, 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 patible 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 15k V dc to 100° C. TX and TXV processing is available.
