一般说明：MAX4820EUP+T
MAX4820EUP+T / MAX4821 8通道继电器驱动器提供内置反冲保护和驱动+ 3.3V / + 5V非锁定或双线圈锁存继电器。这些设备是在驱动+ 3V继电器时特别有用。每个独立开漏输出具有2Ω导通电阻并保证能够吸收70mA（最小值）的负载电流。两种器件的静态消耗均小于50μA（最大值）电流和1μA输出漏电流。
MAX4820EUP+T具有SPI™ - / QSPI™ - / MICROWIRE™ -兼容的串行接口。输入数据转换为8-位移寄存器并在CS时锁存到输出从低到高的过渡。移位寄存器中的每个数据位对应于特定输出，允许独立控制所有输出。
MAX4821具有4位（A0，A1，A2，LVL）并行输入接口。前三位（A0，A1，A2）确定输出地址和第四位（LVL）确定所选输出是否已打开或者关闭。 CS转换时，数据被锁存到输出从低到高。两种器件都具有独立的置位和复位功能允许用户同时打开或关闭所有输出只有一条控制线。内置磁滞（施密特触发器）对所有数字输入都允许使用此设备用于缓慢上升和下降信号，例如来自光耦合器或RC上电初始化的那些电路。 MAX4820EUP+T / MAX4821采用20引脚封装TSSOP和节省空间的20引脚薄型QFN封装。
