描述 Description

These optocouplers are similar to HP’s other high speed transistor optocouplers but with shorter propagation delays and higher CTR. The HCPL-4504/0454 and HCNW4504 also have a guaranteed propagation delay difference (tPLH - tPHL). These features make these optocouplers an excellent solution to IPM inverter dead time and other switching problems.
