Negative terminal of the Channel 1 input LED.

) yield faster rise times at the cost of higher power consumption. Higher values (e.g., 4.7 ) conserve energy but lengthen propagation delays. 1458 optocoupler datasheet

user wants a long article about the "1458 optocoupler datasheet". I need to search for information about this optocoupler. The model number "1458" might not be standard. I should search for "1458 optocoupler" and also "1458 optocoupler datasheet". I'll also search for "optocoupler 1458" and "1458 optoisolator" to cover different naming conventions. I'll use the search tool with these queries. search results show several variants of the "1458 optocoupler", including HCNW1458, HCPL-1458, HCPL-1458-500E, HCPL-A1458, and HCPL1458. These appear to be manufactured by Avago Technologies (now Broadcom). The user likely wants a datasheet for this component. The article should cover the key specifications, features, applications, and possibly include a summary of the datasheet. I will structure the article with an introduction, key specifications, features, applications, and a conclusion. I'll also include a note about where to find the official datasheet. To gather detailed information, I need to open the relevant pages. I'll open the first result (HCNW1458) from kynix.com, the second result (AVAGO - HCPL-1458) from jotrin.com, the third result (HCNW1458) from win-source.net, the fourth result (HCPL-1458-500E) from utsource.us, the fifth result (HCPL-1458-000E) from gorsuelektronik.com, the sixth result (HCPL-A1458) from utsource.net, the seventh result (HCPL1458) from utsource.us, and the eighth result (Optocoupler Datasheets) from datasheet4u.com. I'll also open the search results for "1458 optocoupler" and "1458 optoisolator" to gather more information. search results provide a range of information on the various "1458" optocoupler models. I have enough to write a comprehensive article. I will structure the article with an introduction explaining that "1458 optocoupler datasheet" is not a single part number but refers to a family of optocouplers from Broadcom/Avago, which I will outline. The article will then cover the main part number variants (HCPL-1458, HCPL-1458-500E, HCPL-A1458, HCNW1458, etc.), their key features and specifications, common applications, safety approvals, download sources for the datasheet, and conclude with a summary. I will cite the sources. search for a "1458 optocoupler datasheet" can be confusing because it points to a family of high-performance optocouplers rather than a single device.

: Usually NC (No Connection) or specific anode/cathode pins. Pin 2 : Anode (Input LED). Pin 3 : Cathode (Input LED). Pin 5 : GND (Output side). Pin 6 : Vout (Output Signal). Pin 7 : NC or Enable. Pin 8 : Vcc (Supply Voltage). Common Applications

The HCPL-1458 is generally available in an 8-pin Small Outline Package (SOP-8). Proper understanding of the pinout is essential for correct PCB design. SOP-8 Pin Configuration (Typical) Input side power supply. VINcap V sub cap I cap N end-sub (Cathode): Input signal voltage. NC (No Connection): No internal connection. GND1: Input side ground. GND2: Output side ground. VOUTcap V sub cap O cap U cap T end-sub (Output): Open collector output. NC: No internal connection. $V_CC$2: Output side power supply. Typically available in SOP-8 (SOIC) or 8-pin DIP packages

The HCPL-1458 is typically housed in an or DIP-8 package. While specific internal diagrams vary by variant, a standard high-speed 8-pin optocoupler often follows this general layout:

When interfacing microcontrollers with heavy industrial loads (like relays, motors, or high-power actuators), the HCPL-1458 shields the delicate silicon from inductive kickback or catastrophic shorts. 2. High-Speed Digital Line Receivers

The emitter and detector are physically separated by a transparent dielectric insulation barrier, ensuring no direct electrical path exists between the input and output. 2. Pin Configuration and Package Dimensions

This light-based transmission path ensures that there is no direct electrical connection between the input and output, protecting the control circuitry from electromagnetic interference (EMI) and power surges. LTC1458/LTC1458L - Analog Devices

A common use case for the 1458 optocoupler is isolating a 3.3V or 5V MCU from a noisy industrial subsystem (like a 12V or 24V relay control matrix).

The 1458 optocoupler datasheet highlights several key features that make this device suitable for a wide range of applications. Some of the key features include:
