1458 Optocoupler Datasheet Jun 2026

The 1458 optocoupler is widely used in a variety of applications where high voltage insulation and efficient signal transfer are required. Some of the common applications include:

A high-gain NPN Phototransistor (often with the base pin exposed for external tuning and bias filtering). 2. Pin Configuration (DIP-6 Package) 1458 optocoupler datasheet

When an external control circuit applies current to Pins 1 and 2, the internal GaAs IR LED glows. The brightness of the light is directly proportional to the forward current ( IFcap I sub cap F The 1458 optocoupler is widely used in a

In audio systems or sensor networks, two circuits might have different ground potentials. Connecting them directly burns traces. Placing an optocoupler between the sensor's ground and the microcontroller's ground breaks the loop while passing data. Pin Configuration (DIP-6 Package) When an external control

For use in commercial and industrial products, these optocouplers are certified by major safety organizations. They are typically under UL1577, CSA Approved , and many comply with the IEC/EN/DIN EN 60747-5-2 standard for reinforced insulation.

is a premier single-channel, high-speed optocoupler designed for robust signal isolation in modern, low-voltage electronic systems . Manufactured by Avago Technologies (now Broadcom/Avago), this component is engineered to provide high-speed data transmission while maintaining high common-mode transient immunity (CMR), making it an ideal choice for digital logic ground isolation, industrial control, and communication interfaces.
