| Status: | Unknown |
|---|---|
| Series: | IL221AT, IL222AT, IL223AT |
| RoHS: | Compliant |
Features
| Isolation test voltage, 4000 VRMS |
| Industry standard SOIC-8 surface mountable package |
| Standard lead spacing, 0.05" |
| Applications |
|---|
| TheIL221AT, IL222AT, IL223AT are high current transfer ratio (CTR) optocoupler with a gallium arsenide infrared LED emitter and a silicon NPN photodarlington transistor detector. |
| Thedevice has a CTR tested at 1.0 mA LED current. This low drive current permits easy interfacing from CMOS to LSTTL or TTL. |
| Thisoptocoupler is constructed in a standard SOIC-8 foot print which makes it ideally suited for high density applications. In addition to eliminating through-hole requirements, this package conforms to standards for surface mount devices. |
