Sensing and Control Photologic® Optically Coupled Isolator OPI125, OPI126, OPI127, OPI127-032, OPI128 Features: Data rates to 250 KBit/s Four output op ons 15 kV input‐to‐output isola on voltage Herme cally sealed TX‐TXV process available Direct TTL/STTL interface UL File No. E 58730* High noise immunity Descrip on: Each OPI125, OPI126, OPI127, OPI127‐032 and OPI128 consists of an op cally coupled isolator with a gallium arsenide infrared emi ng diode coupled to a monolithic integrated circuit. This circuit incorporates a photodiode, a linear amplifier and a Schmi trigger on a single silicon chip. For maximum long‐term stability, both the diode and the Photologic® sensor are herme cally sealed in separate packages and then mounted in a high dielectric plas c housing. These devices feature TTL/LSTTL compa ble logic level output that can drive up to 8 TTL loads directly without addi onal circuitry. Also featured are medium‐speed data rates to 250 KBit/s, with typical rise and fall mes of 70 nanoseconds. *UL recogni on is for 15KVDC to 100° C. TX and TXV processing is available.
