The HCPL-1458 resolves this issue by implementing a . By using a dedicated photodiode array to capture the optical emission from the GaAsP LED and feeding that directly to an integrated high-gain amplifier stage, the device dramatically isolates and reduces internal capacitances. This specialized design structure allows the device to function up to a hundred times faster than conventional alternatives. Primary Applications 1458 optocoupler datasheet
Industry-standard single-channel 1 MBd high-speed optocouplers that match the diode-transistor topology and SOP-8/DIP-8 layouts.
For a traditional phototransistor output, CTR is a key indicator of efficiency. However, for the HCPL-1458 high-speed series, which often has a logic gate output, this is sometimes less relevant than its speed characteristics.
The "1458" optocoupler (assumed common through-hole transistor-output optocoupler family; e.g., generic PC817-like single-channel phototransistor optocoupler) provides electrical isolation between input (LED) and output (phototransistor). Typical use cases: microcontroller isolation, signal level shifting, noise suppression, and protecting low-voltage logic from high-voltage circuits. CTR is calculated as: CTR = (IC /
