De scrip tion
The 3C92C is an optically coupled
isolator consisting of an infrared emitting
diode and an NPN silicon phototransistor
mounted in a hermetically sealed TO-72
package.
Typical screening and lot acceptance
tests are provided on page 13-4.
The 3C92CHR device has been 100%
screened as a TXV device although
Group B and C testing is not performed.
