Make sure you have these installed for the application to work properly.
Note that the output is often an open collector, meaning you will need a pull-up resistor to define the logic "High" state. 📋 Guide to Reading the Datasheet
Programmable Logic Controllers (PLCs) handle highly noisy environments packed with heavy inductive motor kicks and electromagnetic interference (EMI). The A1458 acts as a digital buffer between raw field inputs (like proximity sensors or limit switches) and the low-voltage processor core to shield logic gates from damage. 2. Power Transistor Gate Drives
Traditional optocouplers suffer from high base-collector capacitance in their phototransistors, slowing down switching. Devices like the HCPL-A1458 bypass this by utilizing a separate photodiode detector paired with integrated amplification, boosting speed up to 100 times.
Note: All typical specifications and test conditions should be confirmed from the official manufacturer's datasheet, as variations may exist.
) times if you are using this for PWM (Pulse Width Modulation) or high-frequency communication.
The is likely a standard DIP-4 phototransistor optocoupler with medium speed (10 µs) and 3.75kV isolation. Before purchasing:
However, I can help you in other ways:
Connect Pin 8 to the 12V/24V supply. Place a pull-up resistor ( ) between Pin 8 ( VCCcap V sub cap C cap C end-sub ) and Pin 6 ( VOUTcap V sub cap O cap U cap T end-sub
To use any component effectively, you must understand its absolute maximum ratings and electrical characteristics. Below is a distilation of the official .
