1458 Optocoupler Datasheet ^hot^ Info

Keep in mind that the specific details may vary depending on the manufacturer and the particular variant of the 1458 optocoupler. Always consult the datasheet from the manufacturer you're using for the most accurate information.

– Left floating; provides physical spacing to increase the breakdown voltage between the input and output stages.

The HCPL-1458 integrates a high-efficiency Gallium Arsenide Phosphide (GaAsP) Light Emitting Diode (LED) on the input side. This LED is optically coupled to an integrated, high-gain, high-speed photodetector chip on the output side.

: Rated for an isolation voltage of 5300 Vrms . Low Power Consumption : Maximum supply current ( ICCcap I sub cap C cap C end-sub

Provides high transient immunity (up to 50 kV/μs), which protects signals from high-frequency noise. Hermetic Sealing: Packaged in a hermetically sealed SOP-8

Trade-off: This bleeds off some of the optically generated base current, which decreases the overall CTR (sensitivity) but significantly increases the switching speed for PWM applications. 7. Troubleshooting and Best Practices Keep in mind that the specific details may

: Protecting microcontrollers from high-voltage spikes and ground loops.

The HCPL-1458 is an efficient, high-performance optocoupler designed for modern, low-voltage, high-speed digital systems. Its ability to provide robust electrical isolation while adhering to tight space and power requirements makes it a preferred choice for engineers in industrial and commercial applications. For detailed design calculations, always refer to the full from the manufacturer.

This section lists the maximum values that the component can withstand without being damaged:

Standard optocouplers like the 4N35 are slow (µs range). They cannot pass high-speed data (e.g., I²C at 400 kHz or SPI at 10 MHz). For high speed, use dedicated logic optocouplers (e.g., 6N137).
