Description: lpd6803是深圳英盛美半导体公司出品的一款高性能led驱动芯片,该芯片具有如下特点:
三路输出,恒流驱动:每路各有一个外挂电阻调整电流:Iout(max)=30mA, Vout(max)=12V。
兼容恒压模式,可直接替换ZQL9712等常规芯片。
直接PWM输出,无亮度损失,降低数据传输量,有效减少电磁干扰(EMI)。
支持32级灰度/256级灰度(内置反伽码校正逻辑)两种模式,扫描频率高(>4000HZ)。
仅需时钟线/数据线的两线传输结构,级联能力超强。
内建振荡器,支持FREE-RUN模式,降低控制电路成本。
内置LDO稳压电路,电源适应范围宽(4.8-8V),输出耐压高(LED灯供电电压可达12V)。
简化外围配套,可扩充性好,也可作为PWM发生器控制大电流器件驱动大功率LED灯。
该芯片特别适合用于led幕墙灯、led全彩点光源、广告字、异型屏等产品,相对于9712/6106/595/5026/62726等芯片来说,外围器件少,电路简单,
布线容易,使用电线节省,控制器也简单。

Description: 找了很久才找到的。现上传上来共享。
M74HC595 是一个八位串行输入,平行输出的位移缓存器;平行输出为三态输出。在SCK 的上升缘,串行数据由SDI输入到内部的八位位移缓存器,并由Q7’输出。
而平行输出,则是在LCK 的上升缘,将在八位位移缓存器的数据存入到八位平行输出缓存器。当OE 的控制讯号为低致能时, 平行输出端的输出值,等于平行输出缓存器所储存的质。而当OE 的控制讯号为高电位,也就是输出关闭时,平行输出端会维持在高阻抗状态。.
M74HC595 保持了和一般74HC595 功能上以及脚位上的兼容性之外,并针对一些特性予以强化。这些强化的特性,使得M74HC595 非常适合用于像是LED 数组指示器、LED 讯号显示矩阵等需要较大的灌电流应用。每个通道可接受的灌电流都被加大了,使得M74HC595 可以支持更大的LED 电流。而增大的接地电流,可支持数个平行输入通道的同时打开,并灌大电流。比起传统的74HC595,平行输出端同时有较大灌电流时,可靠度增强了四倍以上。
