一般說明：MAX4820EUP+T
MAX4820EUP+T/ MAX4821 8通道繼電器驅動器提供內置反沖保護和驅動+ 3.3V / + 5V非鎖定或雙線圈鎖存繼電器。這些設備是在驅動+ 3V繼電器時特別有用。每個獨立開漏輸出具有2Ω導通電阻并保證能夠吸收70mA（最小值）的負載電流。兩種器件的靜態消耗均小于50μA（最大值）電流和1μA輸出漏電流。
MAX4820EUP+T具有SPI™ - / QSPI™ - / MICROWIRE™ -兼容的串行接口。輸入數據轉換為8-位移寄存器并在CS時鎖存到輸出從低到高的過渡。移位寄存器中的每個數據位對應于特定輸出，允許獨立控制所有輸出。
MAX4821具有4位（A0，A1，A2，LVL）并行輸入接口。前三位（A0，A1，A2）確定輸出地址和第四位（LVL）確定所選輸出是否已打開或者關閉。 CS轉換時，數據被鎖存到輸出從低到高。兩種器件都具有獨立的置位和復位功能允許用戶同時打開或關閉所有輸出只有一條控制線。內置磁滯（施密特觸發器）對所有數字輸入都允許使用此設備用于緩慢上升和下降信號，例如來自光耦合器或RC上電初始化的那些電路。MAX4820EUP+T/ MAX4821采用20引腳封裝TSSOP和節省空間的20引腳薄型QFN封裝。
