Optocoupler, Phototransistor Output
(Dual, Quad Channel)
ILD74, ILQ74
Vishay Semiconductors
DESCRIPTION
The ILD74, ILQ74 is an optically coupled pair with a GaAIAs
infrared LED and a silicon NPN phototransistor. Signal
information, including a DC level, can be transmitted by the
device while maintaining a high degree of electrical isolation
between input and output.
The ILD74, ILQ74 is especially for driving medium-speed
logic, where it may be used to eliminate troublesome ground
loop and noise problems. Also it can be used to replace
relays and transformers in many digital interface
applications, as well as analog applications such as CTR
modulation.
The ILD74 has two isolated channels in a single DIP
package; the ILQ74 has four isolated channels per package.
FEATURES
• ILD74, ILQ74 TTL compatible
