Supports high-speed data transmission over isolation barriers. SOP-8 / DIP-8 (Hermetic) Compact surface-mount or rugged through-hole footprint. Output Type Open Collector
Typically 8 ns to 35 ns (depending on specific testing conditions and sub-variants like the HCPL-1458#060), allowing for high-frequency signal transmission.

Assume a mistaken desire to use a "1458 optocoupler" – instead, we select the .
However, many manufacturers (especially in the relay and industrial control sectors) produce optocouplers housed in "1458" style packages, or use markings similar to date codes (like "Week 14 of 1958") that can be mistaken for part numbers. This public link is valid for 7 days
Before you can use the device, you need to understand how to connect it. The datasheet will provide a pinout diagram and a functional block diagram showing the internal workings.
The HCPL-1458 stands out in the optoelectronics landscape due to its ability to operate reliably at lower logic levels without compromising data speed. Specification Value Description 3.0V to 5.5V Ideal for both legacy 5V TTL and modern 3.3V CMOS systems. Propagation Delay 35 ns (Typical at 10 kHz) Can’t copy the link right now
