MAX6951CEE集成电路（IC）的显示驱动器规格书PDF中文资料

General Description

The MAX6950/MAX6951 are compact common-cathode display drivers that interface microprocessors to individual 7-segment numeric LED digits, bar graph, or discrete LEDs through an SPI™-, QSPI™-MICROWIRE™- compatible serial interface. The supply voltage can be as low as 2.7V.

The MAX6950 drives up to five 7-segment digits or 40 discrete LEDs. The MAX6951 drives up to eight 7-segment digits or 64 discrete LEDs.
