The HT16K33 with LED Drivers SOP-24_300mil RoHS manufactured by Holtek is a low-power CMOS segment display driver designed for LCD and LED applications. This chip consists of a 16-bit LED driver, clock oscillator circuit, multiplex scanning circuit, and a key scan circuit, making it ideal for applications that require matrix display and key scanning. It supports up to 24 common anode pins, allowing it to drive a maximum of 128 LEDs. The LED driver includes two 8-bit brightness control registers to control the 8-bit brightness from 0 to 255. Additionally, this chip includes a power-down register that can be used to set the display into low-power mode. The SOP-24_300-mil RoHS package meets environmental standards and is RoHS compliant.
