Product Summary

The STLED316MTR is a compact LED controller and driver that interface microprocessors to LED displays through serial 3-wire interface. It drives LED connected in common anode configuration. The STLED316MTR drives up to 48 discrete LEDs in 8 segment/6 digit configuration while functioning from a supply voltage of 5.0V. Additionally it can be used to drive 8 discrete LEDs which form a part of LED digit. The individual LEDs are wired as segments of a digit and brightness of these individual LEDs can be controlled digitally. The applications of the STLED316MTR include Set Top Boxes, White goods, Home appliances, DVD players, VCRs.

Parametrics
