OPI125, OPI126, OPI128 Features: Data rates to 250 KBit/s Multiple output options Hermetically sealed 15 kV dc input-to-output isolation TX-TXV process available voltage UL File No. E 58730* Direct TTL/STTL interface High noise immunity 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 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 15kV dc to 100 C. TX and TXV processing is available.
