Direct TTL/STTL interface
High noise immunity
Data rates to 250 KBit/s
Herme cally sealed
UL File No. E 58730*
Descrip on:
The OPI127‐032 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.
This device features 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.
