A1458 Optocoupler Datasheet _hot_ Jun 2026

Given the popularity of the A1458 series, counterfeit or substandard parts are a risk in the market. Reliable components can be sourced from:

The receiving sensor is an integrated photodetector coupled to a high-gain logic gate. Unlike standard phototransistors that suffer from slow speeds due to base-collector capacitance, the A1458 isolates the photodiode bias from the output transistor collector. This configuration speeds up signal propagation by a factor of 100. Critical Technical Specifications

) : Max consumption of 1.2 mA per channel for power-sensitive layouts. Pinout Configuration and Packaging

Programmable Logic Controllers (PLCs) handle highly noisy environments packed with heavy inductive motor kicks and electromagnetic interference (EMI). The A1458 acts as a digital buffer between raw field inputs (like proximity sensors or limit switches) and the low-voltage processor core to shield logic gates from damage. 2. Power Transistor Gate Drives a1458 optocoupler datasheet

Based on recommendations in the and industry best practices:

In motor driver or inverter applications, fast-switching power stages create massive

Ideal for high-speed data links like RS-232, RS-485, or CAN bus isolation. Replacement and Equivalents Given the popularity of the A1458 series, counterfeit

The A1458 functions by translating an electrical input signal into optical light, transmitting it safely across an insulated physical boundary, and converting it back into an electrical signal.

The (often referred to as A1458 ) is a high-speed, single-channel logic gate optocoupler manufactured by Broadcom (formerly Avago). It is designed to bridge the gap between high-speed digital circuits while providing excellent electrical isolation. ⚡ Key Specifications

Do not exceed the forward current of 50mA on the input diode. Exceeding 60mA will rapidly degrade the LED's light output, permanently lowering the CTR. This configuration speeds up signal propagation by a

Rated at 5300 Vrms, protecting sensitive control logic from high-voltage spikes. Power Consumption: Low current draw, with ICCcap I sub cap C cap C end-sub maximum around 1.2 mA. Common Mode Rejection (CMR): Very high immunity to noise ( >50is greater than 50 🛠️ Typical Pin Configuration
