The "1458" model number is commonly associated with a series of high-speed optocouplers originally manufactured by , later managed by Avago Technologies , and now part of Broadcom Inc . The most well-known parts in this family include the HCPL-1458 , HCPL-A1458 , HCNW1458 , and HCPL-1458-500E , among others. The is a high-performance part. However
The is a high-performance part. However, because components occasionally go out of production or face supply constraints, designers sometimes need alternatives.
