This refers to the power required for the output detector circuit (the photodiode and the amplifier). The HCPL-1458 is known for its wide supply range, making it highly versatile for systems running on both standard 5V logic and higher voltage rails. 3.

is a high-performance component manufactured by Avago Technologies (now Broadcom) . HCPL-1458 High-Gain Optocoupler The
However, many manufacturers (especially in the relay and industrial control sectors) produce optocouplers housed in "1458" style packages, or use markings similar to date codes (like "Week 14 of 1958") that can be mistaken for part numbers. | Parameter | Symbol | Typical Value |
Delivers exact isolated control signal paths to manage speed and torque loops in high-power AC and DC motor control architectures.
Before diving into the datasheet, let's quickly cover what an optocoupler (also known as an opto-isolator) is. An optocoupler is a component that allows two isolated circuits to communicate with each other through light. It consists of an LED (light-emitting diode) and a photodetector (such as a phototransistor or photodiode) separated by a dielectric material.
to protect internal components from moisture and environmental contaminants. 2. Pin Configuration (SOP-8) While you should always verify with a specific manufacturer's PDF The HCPL-1458 is known for its wide supply
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).
: High-speed, low-power logic gate optocouplers from Broadcom. 6N137 / Go to product viewer dialog for this item.
Go to Mouser, Digi-Key, or LCSC. Type "DIP-6 optocoupler" and sort by CTR. Do not type "1458" unless you want op-amps.
If this works, your "1458 optocoupler" behaves exactly like a 4N35.
