L16B45数据手册UTC中文资料规格书

描述 Description

The UTC L16B45 is designed for LED displays. UTC L16B45contains a serial buffer and data latches which convert serial inputdata into parallel output format. At UTC L16B45 output stage,sixteen regulated current ports are designed to provide uniform andconstant current sinks for driving LEDs within a large range of VFvariations.UTC L16B45 provides users with great flexibility and deviceperformance while using UTC L16B45 in their system design forLED display applications, e.g. LED panels. Users may adjust theoutput 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 outputport. The high clock frequency, 25MHz, also satisfies the systemrequirements of high volume data transmission.
