OPI125

Photologic® Optically Coupled Isolator OPI126, OPI128 Obsolete (OPI125) Features: • Multiple output options • 15 kV dc input-to-output isolation voltage • Direct TTL/STTL interface • High noise immunity • Data rates to 250 KBit/s • Hermetically sealed • UL File No. E 58730* Description: Each 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 15 kV dc to 100° C. Applications: • High voltage isolation between input and output • Electrical isolation in dirty environments • Industrial equipment • Medical equipment • Office equipment Ordering Information Part Number OPI125 Obsolete OPI126 OPI128 Pin # LED Pin # Photologic® 1 Anode 3 Output 2 Cathode 4 VCC 5 Ground LED Peak Wavelength Sensor Photologic® 890 nm Totem Pole 935 nm Open Collector Inverted Open Collector 890 nm Isolation Voltage (,000) tPLH / tPHL Typ (µs) 15 5/5 VCE IF (mA) (Volts) Typ / Max Max 7.5 / 25 35.0 Lead Length / Spacing Length 0.40" / 0.75" 0.75” [19 mm] * See Table RoHS DIMENSIONS ARE IN: General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
