L16B45A
DESCRIPTION
The UTC L16B45A is designed for LED displays. UTC L16B45A contains a serial buffer and data latches which convert serial input data into parallel output format. At UTC L16B45A 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.
UTC L16B45A provides users with great flexibility and device performance while using UTC L16B45A in their system design for LED display applications, e.g. LED panels. Users may adjust the output current from 3m A to 45m A through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. UTC L16B45A guarantees to endure maximum 17V at the output port. The high clock frequency, 25MHz, also satisfies the system requirements of high volume data transmission.
