描述 Description

The ACPL-W454/P454 is similar to Avago Technologies other high speed transistor output optocouplers, but with shorter propagation delays and higher CTR. The ACPL W454/P454 also has a guaranteed propagation delay difference (tPLH - tPHL). These features make the ACPL W454/P454 an excellent solution to IPM inverter dead time and other switching problems.
