ACPL-P454-000E

The ACPL-P454 is similar to Broadcom’s other high speed transistor output optocouplers, but with shorter propagation delays and higher CTR. The ACPL-P454 also has a guaranteed propagation delay difference (tPLH – tPHL). These features make the ACPL-P454 an excellent solution to IPM inverter dead timeand other switching problems. The ACPL-P454 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 photo detector 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.
