manufactured by Broadcom (formerly Avago/Agilent). It is designed specifically for applications requiring reliable signal isolation in harsh environments, such as industrial control and medical equipment. 1. Key Specifications & Performance High-Speed Operation:
Allows for flexible voltage level-shifting, bussing, and ORing. High Immunity
): The open-collector output pin that pulls low when the input LED is active. 1458 optocoupler datasheet
These values determine the optocoupler’s suitability for in medical or industrial power supplies.
Threshold control pin (allows for adjustments to input current requirements). Typical Application Circuit: manufactured by Broadcom (formerly Avago/Agilent)
Operating the component beyond these limits can cause permanent damage to the device. These specifications are typically rated at an ambient temperature ( TAcap T sub cap A ) of 25°C unless specified otherwise. -55°C to +125°C Operating Temperature Range: -40°C to +85°C Isolation Voltage ( VISOcap V sub cap I cap S cap O end-sub ): 3750 VRMScap V sub cap R cap M cap S end-sub VRMScap V sub cap R cap M cap S end-sub (1-minute rating, depending on suffix/manufacturer) Input Diode (Per Channel) Forward Current ( IFcap I sub cap F ): 25 mA Peak Forward Current ( IF,peakcap I sub cap F comma p e a k end-sub ): 50 mA (with brief pulse width) Reverse Voltage ( VRcap V sub cap R ): 5 V Output Detector (Per Channel) Output Current ( IOcap I sub cap O ): 8 mA Supply Voltage ( VCCcap V sub cap C cap C end-sub

The —often listed in datasheets as the NTE1458 or referenced alongside similar industrial optoisolators—is a specialized electronic component designed to provide electrical isolation between two separate circuits. By transferring electrical signals using light waves, it prevents high voltages from damaging sensitive receiving components.
