HCPL-4504-300E

HCPL-4504-300E is a high-CMR, high-speed optocoupler. It contains a GaAsP LED. The LED is optically coupled to an integrated high-gain photo detector. It has short propagation delays and high CTR. It also has a guaranteed propagation delay difference (tPLH-tPHL). These features make the device an excellent solution to IPM inverter dead time and other switching problems. The CTR, propagation delay, and CMR are specified both for TTL and IPM conditions, which are provided for ease of application. Applications include inverter circuits and intelligent power module (IPM) interfacing - high common mode transient immunity (> 10kV/ms for an IPM load/drive) and (tPLH - tPHL) specified, line receivers - short propagation delays and low input-output capacitance, high speed logic ground isolation - TTL/TTL, TTL/CMOS, TTL/LSTTL, replaces pulse transformers - save board space and weight, analogue signal ground isolation - integrated photodetector provides improved linearity over phototransistors.
