A1458 Optocoupler Datasheet Patched
Operates efficiently with low forward currents, making it directly compatible with CMOS and TTL logic circuits.
| Pin Number | Name | Description | |------------|-------------|------------------------------------| | 1 | Anode (A) | Positive terminal of the IR LED | | 2 | Cathode (C) | Negative terminal of the IR LED | | 3 | Emitter (E) | Output phototransistor emitter | | 4 | Collector (C)| Output phototransistor collector |
package. While you should always verify with the official diagram from Broadcom's technical data
The CTR is not linear. It peaks at a certain forward current range (usually between 5mA and 15mA). Designing circuits with too little or too much input current can cause a dramatic drop in performance.
The is a general-purpose, single-channel optocoupler consisting of a Gallium Arsenide (GaAs) infrared emitting diode optically coupled to a silicon NPN phototransistor. It is packaged in a compact 4-pin DIP (Dual In-line Package) with surface-mount (SMD) option available.
This article provides a comprehensive overview of the , covering its key features, functional description, pinout configuration, and typical applications. 1. Introduction to A1458 Optocoupler
) is a high-speed, single-channel optocoupler designed for isolation in high-performance switching applications. It is typically manufactured by Broadcom (formerly Avago Technologies).
Connect Pin 8 to the 12V/24V supply. Place a pull-up resistor ( ) between Pin 8 ( VCCcap V sub cap C cap C end-sub ) and Pin 6 ( VOUTcap V sub cap O cap U cap T end-sub
Optocouplers are essential components in modern electronics, providing electrical isolation between low-power control circuits and high-voltage power systems.
