The ACPL-W454/P454 is similar to other Broadcom 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.The ACPL-W454/P454 CTR, propagation delays, and CMRare specified both for TTL load and drive conditions andfor IPM (Intelligent Power Module) load and driveconditions. Specifications and typical performance plotsfor both TTL and IPM conditions are provided for easeof application.This diode-transistor optocoupler uses an insulatinglayer between the light emitting diode and an integratedphoto detector to provide electrical insulation betweeninput and output. Separate connections for thephotodiode bias and output transistor collector increasethe speed up to a hundred times over that of aconventional phototransistor coupler by reducing thebase-collector capacitance.
