OPI126 Datasheet

OPTICALLY COUPLED ISOLATOR

No Preview Available !

OPI125, OPI126, OPI128
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
TX-TXV process available
UL File No. E 58730*
Description:
Each OPI125, 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 15kV dc to 100° C.
TX and TXV processing is available. For more information, contact your local representative or OPTEK.
