SN74LV164A集成電路（IC）的移位寄存器規(guī)格書(shū)PDF中文資料

SN74LV164A屬于集成電路（IC）的移位寄存器。由德州儀器制造生產(chǎn)的SN74LV164A移位寄存器移位寄存器是低級(jí)邏輯器件，通常用于在串行和并行方式之間轉(zhuǎn)換數(shù)字邏輯信號(hào)形式的數(shù)據(jù)，或在數(shù)字字內(nèi)移動(dòng)數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個(gè)設(shè)備中的一組觸發(fā)器來(lái)實(shí)現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴(kuò)展等應(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會(huì)非常有用。
