帶有中斷輸出、復(fù)位和配置寄存器的低電壓、8位I2C總線和SMBus I/O擴(kuò)展器

PCAL6408A是一款8位通用I/O擴(kuò)展器，通過I2C總線接口為大多數(shù)微控制器系列提供遠(yuǎn)程I/O擴(kuò)展。\n在保持互連最小化的同時(shí)需要額外的I/O時(shí)，NXP I/O擴(kuò)展器提供簡(jiǎn)易的解決方案，例如，在用于連接傳感器、按鈕、鍵區(qū)等附件的電池供電移動(dòng)應(yīng)用中。除提供靈活的GPIO設(shè)置外，還簡(jiǎn)化了運(yùn)行在一個(gè)電壓級(jí)別上的處理器與工作在不同（通常更高）電壓級(jí)別上的I/O器件之間的連接。PCAL6408A具備內(nèi)置電平切換功能，使這些器件在需要在不兼容I/O電壓之間進(jìn)行通信的混合信號(hào)環(huán)境中極其靈活。\n其雙電源軌上1.65 V至5.5 V的寬范圍VDD允許與接口側(cè)(SDA/SCL)的下一代低電壓微處理器和微控制; I2C總線至并行端口擴(kuò)展器\n1.65 V至5.5 V的工作電源電壓范圍\n允許下列項(xiàng)目之間的雙向電壓電平變換和GPIO擴(kuò)展：1.8 V SCL/SDA和1.8 V、2.5 V、3.3 V或5 V端口P\n2.5 V SCL/SDA和1.8 V、2.5 V、3.3 V或5 V端口P\n3.3 V SCL/SDA和1.8 V、2.5 V、3.3 V或5 V端口P\n5 V SCL/SDA和1.8 V、2.5 V、3.3 V或5 V端口P\n\n1 μA的低待機(jī)電流消耗\n施密特觸發(fā)器操作允許在SCL和SDA輸入上進(jìn)行緩慢輸入轉(zhuǎn)變并帶來更好的切換噪音抗擾性：1.8 V時(shí)Vhys = 0.18 V（;
