Optocoupler, Phototransistor Output (Dual, Quad Channel)
DESCRIPTION
The ILD1, ILD2, ILD5, ILQ1, ILQ2 are optically coupled
isolated pairs employing GaAs infrared LEDs and silicon
NPN phototransistor. Signal information, including a DC
level, can be transmitted by the drive while maintaining a
high degree of electrical isolation between input and output.
The ILD1, ILD2, ILD5, ILQ1, ILQ2 are especially designed for
driving medium-speed logic and can be used to eliminate
troublesome ground loop and noise problems. Also these
couplers can be used to replace relays and transformers in
many digital interface applications such as CTR modulation.
The ILD1, ILD2, ILD5 have two isolated channels in a single
DIP package and the ILQ1, ILQ2 have four isolated channels
per package.
