1458 Optocoupler Datasheet Jun 2026

: Typically provides high isolation levels (often cited up to 5300 Vrms for related series like HCPL-A1458) to protect sensitive logic from high-voltage transients.

If you are sourcing components, you can check inventory or download verified datasheets directly through distributors like the Jotrin Electronics HCPL-1458 Portal or the Xecor Components Database.

You can find technical specifications on distributor sites like Alldatasheet or the manufacturer’s product page . 2. Other Components with "1458"

Its high data rate capability makes it an ideal fit for isolated fieldbus communications, including , operating across distinct ground planes. 3. Power Transistor Gate Drivers 1458 optocoupler datasheet

ceramic capacitor near the power supply pin of the output receiving circuit to filter out noise caused by fast switching transitions.

The following appendix provides additional information on the 1458 optocoupler datasheet: : Typically provides high isolation levels (often cited

By providing a comprehensive overview of the 1458 optocoupler datasheet, this article aims to help designers and engineers understand the device's features, specifications, and applications, and to provide a valuable resource for designing and developing applications that utilize this device.

An Arduino (5V logic) needs to switch a 120VAC lamp via a TRIAC. Solution: Use the optocoupler (e.g., MOC3021 – a special TRIAC driver) to bridge the gap. The 1458 is not here; you'd use a dedicated "random phase" optotriac. For DC loads, the 4N35 works perfectly.

High immunity to noise transients (often >50 kV/µs). Supply Voltage: Wide range, often 3.0V to 5.5V. Power Transistor Gate Drivers Ground connection for the

Since you cannot buy a "1458 optocoupler" by that name, here is your shopping list based on performance needs:

For dual-channel versions, such as the HCNW1458, you will have two completely independent optocoupler channels within the same 8-pin package.

Unlike basic four-pin optocouplers like the PC817, which output to a raw phototransistor, the HCPL-1458 features a with a TTL-compatible open-collector output. Core Architectural Features:

Maintain a minimum distance of 5mm to 8mm between the copper traces on the input side (Pins 1–4) and the output side (Pins 5–8).
