A4504

Product Summary

The A4504 is a high CMR, high speed optocoupler. The optocoupler is similar to HP’s other high speed transistor optocouplers but with shorter propagation delay and higher CTR. The A4504 also has a guaranteed propagation delay difference (tPLH - tPHL). These features make the optocoupler an excellent solution to IPM inverter dead time and other switching problems. The A4504 CTR, propagation delay, and CMR are specified for both TTL and IPM load/drive conditions. Specifications and typical performance plots for both TTL and IPM conditions are provided for ease of application. The single channel, diodetransistor optocoupler is available in 8-Pin DIP, SO-8, and Widebody package configuration. An insulating layer between a LED and an integrated photodetector provides electrical insulation between input and output. The applications of the A4504 include Inverter circuits andintelligent power module(IPM) interfacing, Line Receivers, High Speed Logic Ground Isolation - TTL/TTL, TTL/CMOS, TTL/LSTTL, replaces pulse transformers, Analog Signal Ground Isolation.
