APPLICATION NOTE 1879
Using Maxim SPI-compatible Display Drivers with other SPI
Peripherals

Abstract: This application note discusses techniques to connect Maxim's daisy-chained SPI-compatible display
drivers and GPIO to 3-state SPI devices.


This application note discusses techniques to connect Maxim's SPI-compatible display drivers to other SPI
devices on a common SPI interface. The discussion applies to the MAX6950, MAX6951, MAX6952, MAX6954,
MAX6957, and MAX7221 LED drivers, the MAX6850, and MAX6852 vacuum fluorescent display (VFD) controllers,
and the MAX7301 general purp
