The TLP718F(D4-TP,F) with Optocouplers SDIP-6 RoHS manufactured by Toshiba is an optically isolated unipolar Hall-effect switch and is designed for use in industrial automation, ATE (Automatic Test Equipment), and consumer applications. It has a low power consumption of only 0.25 mW, a high speed, and a wide operating temperature range of -40°C to 85°C. It is designed in a SDIP-6 RoHS package, which is compliant with the European Union's Restriction of Hazardous Substances (RoHS) Directive. It has an LED coupled with a photo diode that functions as an optical isolator, allowing data to be passed from one circuit to another without being affected by noise from the external environment. Its features include low operating voltage from 2.5 to 4.5 volts, high speed response as fast as 8 microseconds, high-temperature resistant package, and high sensitivity.
