TCDT1120(G) Series
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The TCDT1120(G) series consists of a phototransis-
tor optically coupled to a gallium arsenide
infrared-emitting diode in a 6-lead plastic dual inline
package.
The elements are mounted on one leadframe using
a
coplanar technique,
providing a fixed distance
between input and output for highest safety
requirements.
