Maxim MAX6968 8-Port 5.5V Constant-Current LED Driver Datasheet
The MAX6968 is an 8‑port, open‑drain, constant‑current LED driver that operates from a 3 V to 5.5 V supply and supports a 5.5 V output rating. It uses a 4‑wire serial interface to shift data into an 8‑bit register and latch the output states, allowing cascading of multiple devices.
Key features include up to 55 mA continuous current per output, 3 % current matching between outputs, and operation over a temperature range of –40 °C to +125 °C. The device is supplied in TSSOP, PDIP, and SSOP packages and is intended for applications such as signage, architectural lighting, and multiplexed LED displays.
