DESCRIPTION
The IL250/251/252/ILD250/251/252 are bidirectional input
optically coupled isolators consisting of two gallium arsenide
infrared LEDs coupled to a silicon NPN phototransistor per
channel.
The IL250/ILD250 has a minimum CTR of 50 %, the IL251/
ILD251 has a minimum CTR of 20 %, and the IL252/ILD252
has a minimum CTR of 100 %.
The IL250/IL251/IL252 are single channel optocouplers. The
ILD250/ILD251/ILD252 has two isolated channels in a single
DIP package.
FEATURES
• AC or polarity insensitive input
• Built-in reverse polarity input protection
• Improved CTR symmetry
• Industry standard DIP package
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
APPLICATIONS
• Ideal for AC signal detection and monitoring
AGENCY APPROVALS
• UL1577, file no. E52744 system code H or J, double
protection
• CSA 93751
• BSI IEC 60950; IEC 60065
• DIN EN 60747-5-5 available with option 1
