DESCRIPTION
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
The TCET2600/TCET4600 consists of a phototransistor
optically coupled to 2 gallium arsenide infrared-emitting
diodes in 8 pin or 16 lead plastic dual inline package.
The elements are mounted on one leadframe providing a
fixed distance between input and output for highest safety
requirements.
APPLICATIONS
• Computer peripheral interface
• Microprocessor system interface
• Telecom equipment
