GENERAL DESCRIPTION
Communication with the outside world is catered for by including a fully integrated serial interface function, which provides designers with a means of easy communication with external peripheral hardware. In this way, many devices can be cascaded together to drive larger LED displays. Furthermore, with this serial-to-serial or serial-to-parallel structure, the device is very suitable as a replacement for the 74HC595, in applications and related products which include an 8-bit serial input and serial or parallel output.APPLICATIONS
