NTE3094
Optoisolator
Dual, High Speed, Open Collector NAND Gate
Description:
The NTE3094 consists of a pair of inverting optically coupled gates each with a GaAsP emitting diode
and a unique integrated detector. The photons are collected in the detector by a photodiode and then
amplified by a high gain linear amplifier that drives a Schottky clamped open collector output transis-
tor. each circuit is temperature, current and voltage compensated.
This unique isolator design provides maximum DC and AC circuit isolation between input and output
while achieving LSTTL/TTL circuit compatibility. The isolator operational parameters are guaranteed
from 0擄 to +70擄C, such that a minimum input current of 5mA will sink an eight gate fan鈥搊ut (13mA)
at the output with 5 volt V
CC
applied to the detector. This isolation and coupling is achieved with a
typical propagation delay of 57ns.
