Everlight Electronics has introduced two single channel 6-pin SDIP 1Mbit/s and
10Mbit/s transistor output optocouplers. With half the dimensions of
comparable 8-Pin 6N13X devices, they are both suited for use in
space constraint industrial applications.
Both ELS511 and ELS611 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 9.7 x 4.58 x 3.38mm, half of those of a 6N13X series
(8-Pin), eases the use in designs with limited PCB area to make them
perfect for space constraint industrial applications like high speed ground
