Description

The ACPL-M484/P484/W484 fast-speed optocoupler contains a

AlGaAs LED and photo detector with built-in Schmitt trigger to

provide logic-compatible waveforms, eliminating the need for

additional wave shaping. The totem pole output eliminates the

need for a pull-up resistor and allows for direct drive Intelligent

Power Module or gate drive. Minimized propagation delay

difference between devices makes these optocouplers

excellent solutions for improving inverter efficiency through

reduced switching dead time.
