DESCRIPTION
The MC300 microcoupler is a single channel optocoupler consisting of an LED optically coupled to a light sensitive high
speed phototransistor. Each microcoupler is provided with full 100% DC testing (+125C test option upon request) or
100% element evaluation. All microcouplers are capable of operating over the full military temperature range.

NOTES:
1.
CURRENT TRANSFER RATIO is defined as the ratio of output collector current, I
O
, to the forward LED input current., I
F
, times 100%.
2.
Measured between input pins shorted together and the output pins for that channel shorted together.
