A1458 Optocoupler Datasheet 2021 〈99% Essential〉

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

Usually Pins 2 (Anode) and 3 (Cathode) for the GaAsP LED. Output Side: Pins 5 (GND), 6 ( VOUTcap V sub cap O cap U cap T end-sub ), and 8 ( VCCcap V sub cap C cap C end-sub a1458 optocoupler datasheet

that is TTL compatible, allowing it to interface directly with microcontrollers and digital logic. Common packages include The (often referred to as A1458 ) is

: 3750 Vrms to 5000 Vrms (depending on the specific package and testing standard). Environmental Operating Temperature : Ranges from -40°C to +85°C. Pinout and Package The A1458 is typically housed in an 8-pin SOP (Small Outline Package) DIP-8 package Input Side

The reveals a robust, versatile, and reliable component for medium-speed, high-isolation applications. It is not the fastest optocoupler (do not use it for RS-485 or CAN bus isolation), nor is it the cheapest (the PC817 is slightly more economical). However, the A1458 shines in its excellent CTR consistency, wide temperature range, and high 5000Vrms isolation.
