DESCRIPTION
The MC024 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.
