1458 Optocoupler Datasheet Jun 2026

(often marked as a photocoupler or isolation IC), it is likely a standard 4-pin or 6-pin DIP optocoupler similar to the industry-standard PC817 or 4N35 series.

F bypass capacitor as close as possible between Pin 5 (GND) and Pin 8 ( VCCcap V sub cap C cap C end-sub

Note: If your chip has 6 pins (like a 4N35), Pins 3, 4, 5, and 6 correspond to the Base, Collector, and Emitter. Always check the physical datasheet if possible. 1458 optocoupler datasheet

Due to its combination of fast response times and low power dissipation, the 1458 optocoupler series serves as a critical bridge in several topologies: Single Channel, High Speed Optocouplers Technical Data

Operating the device beyond these limits can cause permanent physical degradation or immediate component failure. All ratings are measured at an ambient temperature ( TAcap T sub cap A ) of 25°C unless otherwise specified.

: Commonly available in a hermetically sealed 16-DIP or SOP-8 package for high-reliability environments. Review: Pros & Cons HCPL-1458 Avago - Xecor

The is a high-speed, dual-channel logic gate optocoupler often manufactured by Broadcom (formerly Avago/Agilent) . It is designed for applications requiring robust electrical isolation and fast data transmission, such as industrial control and telecommunications. Key Specifications According to technical data , the HCPL-1458 features: Channels : 2 unidirectional channels. Data Rate : Up to 10 MBd (10 Mbps). Due to its combination of fast response times

The 1458 optocoupler datasheet provides a comprehensive overview of the device's features, specifications, and applications. By understanding the device's performance and characteristics, designers and engineers can develop applications that utilize the 1458 optocoupler to provide high voltage insulation and efficient signal transfer. Whether you're designing a power supply, motor control circuit, or industrial automation system, the 1458 optocoupler datasheet is an essential resource that can help you get the job done.

Unlike single-channel optocouplers (like the ubiquitous 4N25 or PC817), the 1458 architecture is optimized for space-constrained designs requiring multiple isolated channels, high common-mode rejection (CMR), and predictable switching speeds. It is frequently utilized in industrial automation, data communications, and power supply feedback loops. 2. Internal Block Diagram and Pinout Configuration
