Optocouplers offer speed increase in limited space

Everlight Electronics has announced the introduction of two single channel 6-pin SDIP 1Mb/s and 10Mb/s transistor output optocouplers. With merely half the dimensions of comparable 8-Pin 6N13X devices, they are both suited for use in space constrained industrial applications. The ELS511 and ELS611 optocouplers are SMD devices in a small outline 6-pin SDIP package.

The ELS511 series devices each consist of an infrared emitting diode, optically coupled to a high speed photo detector transistor. A separate connection for the photodiode bias and output-transistor collector increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor. The ELS611 series devices consist of an infrared emitting diode optically coupled to a high speed integrated photo detector logic gate with a storable output.

Their dimensions of 9.7x4.58x3.38mm, half of those of a 6N13X series (8-Pin), greatly eases use in designs with limited PCB area, making them suitable for space constrained industrial applications like high speed ground isolation.
