I2C 16位GPIO擴展

NCA9555是一款24引腳CMOS器件，提供16位通用并行I2C總線數(shù)輸入/輸出GPIO擴展功能。它和ACPI電源開關，傳感器，按鍵，LED和風扇等應用的額外I/O口需求提供了簡單的解決方案。NCA9555由兩個8位配置(輸入或輸出選擇)組成。輸入，輸出和極性反轉(高電平有效或低電平有效)寄存器。通過寫入I/O配置位，系統(tǒng)主機可以將I/O啟用為輸入或輸出。每個輸入或輸出的數(shù)據(jù)都保存在相應的輸入或輸出寄存器中。讀寄存器的極性可以用極性反轉寄存器反轉。系統(tǒng)主機可以讀取所有寄存器。當任何輸入狀態(tài)與其對應的輸入端口寄存器狀態(tài)不同時，NCA9555漏極開路中斷輸出將被激活，并用于向系統(tǒng)主設備指示輸出狀 ?工作電源電壓范圍為2.3V至5.5V\n?I2C到并行端口擴展器\n?極性反轉寄存器\n?開漏電路低電平有效中斷輸出\n?與大多數(shù)MCU兼容\n?16個I/O引腳，默認為16個輸入\n?低待機電流\n?ESD保護性能超出JESD22標準\no2000V人體充放電模型(A114-A)\no1000V充電器件模型(C101)\n?3個地址引腳，支持8個不同地址\n?0~400kHz時鐘頻率\n?閂鎖性能超過100mA\n?工作溫度：-40℃~85℃\n?符合RoHS的封裝：TSSOP24;
