DESCRIPTION
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. LED panels. Users may adjust the output current from 3mA to 45mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. UTC L16B45 guarantees to endure maximum 17V at the output port. The high clock frequency, 25MHz, also satisfies the system requirements of high volume data transmission.●
FEATURES
