  • Improving System Interrupt Management Using the PCF8574 and PCF8574A I/O Expande
    PDF, 216 Kb, Datei veröffentlicht: Jul 27, 2001
    In today?s complex, embedded, computing and data-communication systems, interrupts areused extensively to service peripheral devices. However, because of the pin-numberlimitation on packages, most microprocessors have only one or two interrupt lines.Consequently, several devices usually are connected to the same interrupt line. Thedrawback to this configuration is that the overhead process

    The I2C bus is a very popular and powerful bus used for communication between a single (or multiple)master and a single (or multiple) slave device. In many applications there is a potential need for moreslave devices on the bus, isolation between similar addressed slaves, or a need for more I/Os. Theseneeds can be solved with an I2C buffer, switch, and I/O expander.The application note h
