L16B45 Overview
The UTC L16B45 is designed for LED displays. UTC L16B45 contains a serial buffer and data latches which convert serial input data into parallel output format. At UTC L16B45 output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.
