Description:

The OPI127‐032 consists of an optically coupled isolator with a gallium arsenide infrared emiƫng diode coupled to a monolithic integrated circuit. This circuit incorporates a photodiode, a linear amplifier and a SchmiƩ 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.

This device features 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 15KVDC to 100° C.
