1-Wire、8通道、可編址開關(guān)

DS2408是一款8通道、可編程I/O 1-Wire? IC。PIO輸出可配置為開漏結(jié)構(gòu)，具有100Ω的最大導(dǎo)通電阻。穩(wěn)固的PIO通道訪問通信協(xié)議確保PIO輸出設(shè)置變化沒有誤差。數(shù)據(jù)有效選通輸出，可用來鎖存PIO的邏輯狀態(tài)，供給外部電路，如D/A轉(zhuǎn)換器(DAC)或微控制器的數(shù)據(jù)總線。\n\n DS2408的工作受單線連接的1-Wire總線控制，器件通信遵從于標(biāo)準(zhǔn)的Dallas Semiconductor 1-Wire協(xié)議。每片DS2408都具有自己的64位ROM注冊碼，這個注冊碼由工廠光刻到芯片內(nèi)。該注冊碼保證其唯一的可識別性，在多點連接的1-Wire網(wǎng)絡(luò)中可以用作地址碼。多片DS2 ? 八通道開漏結(jié)構(gòu)的可編程I/O \n?
