Yes, it's an optocoupler chip. TLP236 1 15Mbps optocoupler provides high output GaAs? As a light-emitting diode coupled with an integrated high-gain and high-speed photodetector. They are located in the SO6 package. These photocouplers are guaranteed to work at a temperature as high as125 C and a power supply of 2.7V-5.5V TLP236 1 ensures a low power supply current (ICCL/ICCH) of 1mA and a low threshold input current (IFHL) of 1.6 mA (TA It can be directly driven by a microcomputer to obtain low input current. It can provide 20kV/μ s guaranteed common-mode transient immunity.
Typical applications include factory networks, high-speed digital interfaces for instruments and control equipment, and I/O interface boards.
