1458 Optocoupler Datasheet Updated -

Adhering to the absolute maximum ratings in the is crucial to prevent permanent damage to the device: Storage Temperature: -55°C to +125°C Operating Temperature: -40°C to +85°C Supply Voltage ( VCCcap V sub cap C cap C end-sub ): 0 to 7.0 V Input Current ( IINcap I sub cap I cap N end-sub ): Low-level currents specified for logic inputs. Output Voltage ( VOcap V sub cap O ): Max 7.0 V. Applications of the HCPL-1458 Optocoupler

In the electronics industry, the number is most famously associated with a Dual Operational Amplifier (like the MC1458 or LM1458). These are analog chips, not optocouplers. They have 8 pins and look identical to an optocoupler IC, but they function completely differently.

Offers quick response times (35 ns at 10 kHz) for fast, real-time control. 1458 optocoupler datasheet

Understanding the pin configuration is crucial for PCB layout and prototyping. Below is the typical 8-pin Dual In-line Package (DIP) layout for a standard 1458 dual-channel optocoupler:

The PC1458 is an optically coupled isolator consisting of a Gallium Arsenide (GaAs) infrared emitting diode (IRED) optically coupled to a silicon phototransistor detector. It is housed in a standard 4-pin DIP (Dual In-line Package). Adhering to the absolute maximum ratings in the

Isolating line receivers and data transmission systems like RS-485 or CAN bus .

" feature, meaning it requires minimal current from a microcontroller's GPIO to trigger. Common Mode Rejection (CMR): These are analog chips, not optocouplers

The Current Transfer Ratio is the ratio of output collector current ( ICcap I sub cap C ) to input forward current ( IFcap I sub cap F ), expressed as a percentage:

Features a propagation delay of approximately 35 ns, making it suitable for fast digital logic. Wide Supply Voltage ( cap V sub cap C cap C end-sub Operates across a range of 3.0V to 5.5V
