OPI125 (TX, TXV) Features: High current transfer ratio 15 kV electrical isolation Direct TTL/LSTTL interface High noise immunity Data rates to 250 KBaud Description: Each OPI125TX and OPI125TXV is an optically coupled isolator that consists of a gallium aluminum arsenide infrared light emitting diode (OP235 TX or OP235TXV) and a monolithic integrated circuit which incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single die (OPL800TX or OPL800TXV), sealed in a high dielectric plastic housing. The device features TTL/LSTTL compatible logic level output which can drive up to 8 TTL loads directly without additional circuitry. Also featured are medium speed data rates to 250 KBaud with typical rise and fall times of 70 nanoseconds. These devices are designed for applications that require high voltage isolation between input and output. TX and TXV device components are processed to OPTEK's military screening program patterned after MIL-PRF-19500. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
