A1458 Optocoupler Datasheet Jun 2026

The A1458 is frequently referenced by its more complete Avago/Broadcom part numbers: (the most common version) and HCPL-A1458 (another variant). These devices are renowned for their exceptional high-speed performance, low power consumption, and high noise immunity.

) on the output side. Place it as close to the pins as physically possible to filter out high-frequency power supply noise.

If your isolated output circuit operates at 24V and requires a clean logic signal into a PLC:Using a standard

The device is widely available in surface-mount SOP-8 or SOIC-8 packages, as well as 8-pin DIP formats for through-hole mounting. Some high-reliability versions are for use in aerospace or harsh industrial environments. HCPL-1458/ A1458 - Broadcom - Price, Inventory & Datasheets a1458 optocoupler datasheet

Ensures efficient signal reproduction from the input primary side to the output secondary side. 2. Pin Configuration and Package Dimensions

Low power draw optimized for dense, multi-channel arrays and battery-operated equipment. Pin Configuration and Package Styles

A digital high signal (e.g., 5V from an Arduino or PLC) passes through a current-limiting resistor into Pin 1 (Anode). The A1458 is frequently referenced by its more
