Broadcom, HCPL-4661-020E DC Input Open Collector, Transistor Output Quad Optocoupler, Through Hole, 8-Pin DIP-8

The Broadcom Optocoupler are optically coupled gates that combine a GaAsP light emitting diode and an integrated high gain photo detector. An enable input allows the detector to be strobed. The output of the detector IC is an open collector Schottky-clamped transistor. This unique design provides maximum AC and DC circuit isolation while achieving TTL compatibility. The optocoupler AC and DC operational parameters are guaranteed from -40°C to 85°C allowing trouble-free system performance.
