IP403 LF数据手册IC+中文资料规格书

描述 Description

The IP403 is a dual-functional controller chip, the serial-to-parallel LED driver. The serial-to-parallel LED driver can replace up to 7 74LV164 glue logic chips. 

When set to LED driver mode, IP403 can directly drive 56 LEDs or 48 LEDs, depending on either single serial input or triple serial input. When set to single serial input mode, all LED driver pins are linked internally with the internal shift registers.

If set to triple serial input mode, each serial input corresponds to 16 LED driver pins, meaning that 48 LEDs driver pins in total.
