ACPL-W454-000E

The ACPL-W454-000E is a 1-channel 6-pin transistor output High Speed Optocoupler for use with line receivers and replace pulse transformers. It has a guaranteed propagation delay difference (tPLH-tPHL). These features make the ACPLW454 an excellent solution to IPM inverter dead time and other switching problems. The ACPL-W454 CTR, propagation delays and CMR are specified both for TTL load and drive conditions and for IPM (Intelligent Power Module) load and drive conditions. Specifications and typical performance plots for both TTL and IPM conditions are provided for ease of application. This diode-transistor optocoupler uses an insulating layer between the light emitting diode and an integrated photodetector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional phototransistor coupler by reducing the base-collector capacitance.
