Greetings! I am replacing a SMD-8 chip with A 450F enscribed on it . I assume that it is a optocoupler made by Avago/Agilent. Normally with A prefixes, the ordering name comes up as HCPL, but searching for HCPL-450F and HP450F doesnt come up with a datasheet or US stock which is really odd. could someone help Identify what this is and the correct naming convention? Thanks!
